Description

The TDA 16846-2 (this name is used in the description for all types) is optimized to

control free running or fixed frequency flyback converters with or without Power Factor

Correction (Current Pump). To provide low power consumption at light loads, this device

reduces the switching frequency in small steps with load, towards an adjustable

minimum (e. g. 20 kHz in standby mode). Additionally, the startup current is very low. To

avoid switching stress on the power devices, the power transistor is always switched on

at minimum voltage. A special circuit is implemented to avoid jitter. The device has

several protection functions: V_CCover- and undervoltage, mains undervoltage, current

limiting and 2 free usable fault comparators. Regulation can be done by using the

internal error amplifier or an opto coupler feedback (additional input). The output driver

is ideally suited for driving a power MOSFET. Fixed frequency and synchronized

operation are also possible.

The TDA 16846-2 is suited for TV-, VCR- sets, SAT receivers and other sets for

consumer electronics. It also can be used in PC monitors.

The TDA 16847-2 is identical with TDA 16846-2 but has an additional power

measurement output (pin 8) which can be used as a Temporary High Power Circuit.

Short Description of the Pin Functions

Function

A parallel RC-circuit between this pin and ground determines the ringing

suppression time and the standby-frequency.

A capacitor between this pin and ground and a resistor between this pin and

the positive terminal of the primary electrolytic capacitor quantifies the max.

possible output power of the SMPS.

This is the input of the error amplifier and the zero crossing input. The output

of a voltage divider between the control winding and ground is connected to

this input. If the pulses at pin 3 exceed a 5 V threshold, the control voltage at

pin 4 is lowered.

This is the pin for the control voltage. A capacitor has to be connected

between this pin and ground. The value of this capacitor determines the

duration of the softstart and the speed of the control (primary regulation).

If an opto coupler for the control is used, its output has to be connected

between this pin and ground. The voltage divider at pin 3 has then to be

changed, so that the pulses at pin 3 are below 5 V.

Fault comparator 2: A voltage > 1.2 V at this pin stops the SMPS (v.also pin 9).

If fixed frequency mode is wanted, a parallel RC circuit has to be connected

between this pin and ground. The RC-value determines the frequency. If

synchronized mode is wanted, sync pulses have to be fed into this pin.

TDA 16846-2: Not connected. TDA 16847-2: This is the power measurement

output of the Temporary High Power Circuit. A capacitor and a RC-circuit has

to be connected between this pin and ground.

Output for the reference voltage (5 V). With a resistor between this pin and

ground the fault comparator 2 (pin 6) is enabled.

Fault comparator 1: If a voltage > 1 V is applied to this pin, the SMPS stops.

This is the input of the primary voltage check. The voltage at the anode of the

primary electrolytic capacitor has to be fed to this pin via a voltage divider. If

the voltage of this pin falls below 1 V, the SMPS is switched off. A second

function of this pin is the primary voltage dependent fold back point correction

(only active in free running mode).

Common ground.

Output signal. This pin has to be connected via a series resistor to the gate of

the power transistor.

Connection for supply voltage and startup capacitor. After startup, the supply

voltage is produced by the control winding of the transformer and rectified by

an external diode.

Functional Description

Start Up Behaviour (Pin 14)

When power is applied to the chip and the voltage V₁₄at Pin 14 (V_CC) is less than the

upper threshold (V_ON) of the Supply Voltage Comparator (SVC), then the input current

I₁₄will be less than 100 µA. The chip is not active (off state) and driver output (Pin 13)

and control output (Pin 4) will be actively held low. When V₁₄exceeds the upper SVC

threshold (V_ON) the chip starts working and I₁₄increases. When V₁₄falls below the lower

SVC threshold (V_OFF) the chip starts again from its initial condition. Figure 4 shows the

start-up circuit and Figure 5 shows the voltage V₁₄during start up. Charging of C₁₄is

done by resistor R₂of the “Primary Current Simulation” (see later) and the internal diode

D1, so no additional start up resistor is needed. The capacitor C₁₄delivers the supply

current until the auxiliary winding of the transformer supplies the chip with current

through the external diode D14.

It is recommended to apply a small RF snubber capacitor of e.g. 100 nF parallel to the

electrolytic capacitor at pin 14 as shown in the application circuits in Figures 15, 16 , and

17.

To avoid multiple pulses during start up in fixed frequency mode (danger of transformer

saturation), the IC works in freerunning mode until the pulses at pin 3 (RZI) exceed the

2.5 V threshold (only TDA 16846-2, TDA 16847-2).

Primary Current Simulation PCS (Pin 2) / Current Limiting

A voltage proportional to the current of the power transistor is generated at Pin 2 by the

RC-combination R₂, C₂(Figure 4). The voltage at Pin 2 is forced to 1.5 V when the

power transistor is switched off and during its switch on time C₂is charged by R₂from

the rectified mains. The equation of V₂and the current in the power transistor (I_primary) is

_primary× I_primary

V₂= 1,5 V+ -------------------------------

R₂× C₂

_primary: Primary inductance of the transformer

The voltage V₂is applied to one input of the On Time Comparator ONTC (see Figure 2).

The other input is the control voltage. If V₂exceeds the control voltage, the driver

switches off (current limiting). The maximum value of the control voltage is the internal

reference voltage 5 V, so the maximum current in the power transistor (I_Mprimary) is

3,5 V × R₂× C₂

I_Mprimary= --------------------------------------

L_primary

The control voltage can be reduced by either the Error Amplifier EA (current mode

regulation), or by an opto coupler at Pin 5 (regulation with opto coupler isolation) or by

the voltage V₁₁at Pin 11 (Fold Back Point Correction).

Fold Back Point Correction PVC (Pin 11)

V₁₁is derived from a voltage divider connected to the rectified mains and reduces the

limit of the possible current maximum in the power transistor if the mains voltage

increases. I.e. this limit is independent of the mains (only active in free running mode).

The maximum current (I_Mprimary) depending on the voltage V₁₁at Pin 11 is

(4 V – V₁₁⁄ 3) × R₂× C₂

I_Mprimary= ------------------------------------------------------------

L_primary

Off-Time Circuit OTC (Pin 1)

Figure 6 shows the Off-Time Circuit which determines the load dependent frequency

curve. When the driver switches off (Figure 7) the capacitor C₁is charged first by current

I_1L(approx. 0.5 mA, for extended ringing suppression time). As soon as the voltage at

pin 3 reaches the level V_3L(2.5 V), the charging current is switched to the higher value

I_1H(approx. 1 mA, for normal ringing suppression time). This current flows until the

capacitor’s voltage reaches 3.5 V. The charge time TC1 is

C₁× 1,5 V

-------------------------

TC1 ≈

1mA

For proper operation of the special internal anti- jitter circuit, TC1 (rising time for I_1Honly)

should have the same value as the resonance time “tR” of the power circuit (Figure 7).

After charging C₁up to 3.5 V the current source is disconnected and C₁is discharged by

resistor R₁. The voltage V₁at Pin 1 is applied to the Off-Time Comparator (OFTC). The

other input of OFTC is the control voltage. The value of the control voltage at the input

of OFTC is limited to a minimum of 2 V (for stable frequency at very light load). The On-

Time Flip Flop (ONTF) is set, if the output of OFTC is high ¹⁾and the voltage V₃at Pin 3

falls below 25 mV (zero crossing signal is high). This ensures switching on of the power

transistor at minimum voltage. If no zero crossing signal is coming into pin 3, the power

transistor is switched on after an additional delay until V₁falls below 1.5 V (see Figure 6,

OFTCD). As long as V₁is higher than the limited control voltage, ONTF is disabled to

suppress wrong zero crossings of V₃, due to parasitic oscillations from the transformer

after switch-off. The discharge time of C₁is a function of the control voltage.

i.e. V₁is less than the limited control voltage.

Error Amplifier EA / Soft-Start (Pin 3, Pin 4)

Figure 9 shows the simplified Error Amplifier circuit. The positive input of the Error

Amplifier (EA) is the reference voltage 5 V. The negative input is the pulsed output

voltage from the auxiliary winding, divided by R₃₁and R₃₂. The capacitor C₃is

dimensioned only for delaying zero crossings and smoothing the first spike after switch-

off. Smoothing of the regulation voltage is done with the soft start capacitor C₄at Pin 4.

During start up C₄is charged with a current of approx. 2 µA (Soft Start). For primary

regulation C₄is charged and discharged with pulsed currents. Figure 10 shows the

voltage diagrams of the Error Amplifier circuit.

Fixed Frequency and Synchronization Circuit SYN (Pin 7)

Figure 11 shows the Fixed Frequency and Synchronization Circuit. The circuit is

disabled when Pin 7 is not connected or connected to pin 9 (Vref, to avoid noise

sensitivity). With R₇and C₇at Pin 7 the circuit is working. C₇is charged fast with approx.

1 mA and discharged slowly by R₇(Figure 11). The power transistor is switched on at

beginning of the charge phase. The switching frequency is (charge time ignored)

When the oscillator circuit is working the Fold Back Point Correction is disabled (not

necessary in fixed frequency mode). “Switch on” is only possible when a “zero crossing”

has occurred at Pin 3, otherwise “switch-on” will be delayed (Figure 12).

Protection Functions

The chip has several protection functions:

Current Limiting

See “Primary Current Simulation PCS (Pin 2) / Current Limiting” and “Fold Back Point

Correction PVC (Pin 11)”.

Over- and Undervoltage Lockout OV/SVC (Pin 14)

When V₁₄at Pin 14 exceeds 16.5 V, e. g. due to a fault in the regulation circuit, the Error

Flip Flop ERR is set and the output driver is shut-down. When V₁₄goes below the lower

SVC threshold, ERR is reset and the driver output (Pin 13) and the soft-start (Pin 4) are

shut down and actively held low.

Primary Voltage Check PVC (Pin 11)

When the voltage V₁₁at Pin 11 goes below 1 V the Error Flip Flop (ERR) is set. E.g. a

voltage divider from the rectified mains at Pin 11 prevents high input currents at a too low

input voltage.

Free Usable Fault Comparator FC1 (Pin 10)

When the voltage at Pin 10 exceeds 1 V, the Error Flip Flop (ERR) is set. This can be

used e. g. for mains overvoltage shutdown.

Free Usable Fault Comparator FC2 (Pin 6)

When the voltage at Pin 6 exceeds 1.2 V, the Error Flip Flop (ERR) is set. A resistor

between Pin 9 (REF) and ground is necessary to enable this fault comparator.

Voltage dependent Ringing Suppression Time

During start-up and short-circuit operation, the output voltage of the converter is low and

parasitic zero crossings are applied for a longer time at Pin 3. Therefore the Ringing

Suppression Time TC1 (see “Off-Time Circuit OTC (Pin 1)”) is extended with a factor of

2.2 at a low output voltage. The voltage at pin 1 must not fall below the limit V1L.

Temporary High Power Circuit FC2, PMO, REF

(Pin 6, 8, 9, TDA 16847-2)

Figure 14 shows the Temporary High Power Circuit:

Figure 14

The Temporary High Power Circuit (THPC) consists of two parts:

Firstly, a power measurement circuit is implemented: The capacitor C₈at Pin 8 is

charged with a constant current I₈during the discharge time of the flyback transformer

and grounded the other time. Thus the average of the sawtooth voltage V₈at Pin 8 is

proportional to the converter´s output power (at constant output voltages). The charge

current I₈for C₈is set by the resistor R₉at Pin 9:

I₈= 5 V/R₉

Version 2.0

31 Jul 2003

TDA 16846/16846-2

TDA 16847/16847-2

Secondly, a High Power Shutdown Comparator (FC2) is implemented: When the voltage

V₆at Pin 6 exceeds 1.2 V the Error Flip Flop (ERR) is set. The output voltage of the

power measurement circuit (Pin 8) is smoothed by R₈/C₆and applied to the “high power

shutdown” input at Pin 6. The relation between this voltage V₆and the output power of

the converter P is approximately:

V₆≈ (P × L_Secondary× 5 V)/(V_OUT²× C₈× R₉)

_Secondary: The transformers secondary inductance

_OUT: The converters output voltage

So the time constant of R₉/C₈for a certain high power shutdown level P_SDis:

R₉× C₈≈ (P_SD× L_Secondary× 4.2)/V_OUT

The converters high power shutdown level can be adjusted lower (by R₉, C₈) than the

current limit level (see “current limiting”). Thus because of the delay R₈/C₆, the converter

can deliver maximum output power (current limit level) for a certain time (e. g. for power

pulses like motor start current) and a power below the high power shutdown level for an

unlimited time. This is of advantage because the thermal dimensioning of the power

devices needs to be done for the lower power level only. Once the voltage V₆exceeds

1.2 V no more charging or discharging happens at Pin 8. The voltage V₆remains high

due to the bias current out of FC2 and the converter remains switched-off. Reset can be

done either by plugging-off the supply from the mains or by a high value resistor R₆

(Figure 14). R₆causes a reset every few seconds. When Pin 9 is not connected or gets

too little current (I9 < I9FC2), the temporary high power circuit is disabled.
