PIN FUNCTION  
Name  
Function  
Power supply of the control circuits. Also provides a charging current during start up thanks to a high  
voltage current source connected to the drain. For this purpose, an hysteresis comparator monitors the  
V
voltage and provides two thresholds:  
DD  
V
- V  
: Voltage value (typically 14.5V) at which the device starts switching and turns off the start up  
DDon  
DD  
current source.  
- V : Voltage value (typically 8V) at which the device stops switching and turns on the start up current  
DDoff  
source.  
SOURCE Power MOSFET source and circuit ground reference.  
Power MOSFET drain. Also used by the internal high voltage current source during start up phase for  
DRAIN  
charging the external V capacitor.  
DD  
Feedback input. The useful voltage range extends from 0V to 1V, and defines the peak drain MOSFET  
current. The current limitation, which corresponds to the maximum drain current, is obtained for a FB pin  
shorted to the SOURCE pin.

RECTANGULAR U-I OUTPUT  
CHARACTERISTIC  
WIDE RANGE OF VDD VOLTAGE  
The VDD pin voltage range extends from 9V to 38V.  
This feature offers a great flexibility in design to  
achieve various behaviors. In figure 8 a forward  
configuration has been chosen to supply the  
device with two benefits:  
– as soon as the device starts switching, it  
immediately receives some energy from the  
auxiliary winding. C5 can be therefore reduced  
and a small ceramic chip (100 nF) is sufficient to  
insure the filtering function. The total start up  
time from the switch on of input voltage to output  
voltage presence is dramatically decreased.  
A complete regulation scheme can achieve  
combined and accurate output characteristics.  
Figure 8 presents a secondary feedback through  
an optocoupler driven by a TSM101. This device  
offers two operational amplifiers and a voltage  
reference, thus allowing the regulation of both  
output voltage and current. An integrated OR  
function performs the combination of the two  
resulting error signals, leading to a dual voltage  
and current limitation, known as a rectangular  
output characteristic.  
This type of power supply is especially useful for  
battery chargers where the output is mainly used in  
current mode, in order to deliver a defined charging  
rate. The accurate voltage regulation is also  
convenient for Li-ion batteries which require both  
modes of operation.  
– the output current characteristic can be  
maintained even with very low or zero output  
voltage. Since the TSM101 is also supplied in  
forward mode, it keeps the current regulation up  
whatever the output voltage is.The VDD pin  
voltage may vary as much as the input voltage,  
that is to say with a ratio of about 4 for a wide  
range application.  
8/15  
VIPer22ADIP / VIPer22AS  
FEEDBACK PIN PRINCIPLE OF OPERATION  
In a real application, the FB pin is driven with an  
optocoupler as shown on figure 9 which acts as a  
pull up. So, it is not possible to really short this pin  
to ground and the above drain current value is not  
achievable. Nevertheless, the capacitor C is  
averaging the voltage on the FB pin, and when the  
optocoupler is off (start up or short circuit), it can be  
assumed that the corresponding voltage is very  
close to 0 V.  
For low drain currents, the formula (1) is valid as  
long as IFB satisfies IFB< IFBsd, where IFBsd is an  
internal threshold of the VIPer22A. If IFB exceeds  
this threshold the device will stop switching. This is  
represented on figure 4, and IFBsd value is  
specified in the PWM COMPARATOR SECTION.  
Actually, as soon as the drain current is about 12%  
of Idlim, that is to say 85 mA, the device will enter  
a burst mode operation by missing switching  
cycles. This is especially important when the  
converter is lightly loaded.  
It is then possible to build the total DC transfer  
function between ID and IFB as shown on figure 10.  
This figure also takes into account the internal  
blanking time and its associated minimum turn on  
time. This imposes a minimum drain current under  
which the device is no more able to control it in a  
linear way. This drain current depends on the  
primary inductance value of the transformer and  
the input voltage. Two cases may occur,  
depending on the value of this current versus the  
fixed 85 mA value, as described above.  
A feedback pin controls the operation of the  
device. Unlike conventional PWM control circuits  
which use a voltage input (the inverted input of an  
operational amplifier), the FB pin is sensitive to  
current. Figure 9 presents the internal current  
mode structure.  
The Power MOSFET delivers a sense current Is  
which is proportional to the main current Id. R2  
receives this current and the current coming from  
the FB pin. The voltage across R2 is then  
compared to a fixed reference voltage of about  
0.23 V. The MOSFET is switched off when the  
following equation is reached:  
R2 (IS + IFB) = 0.23V  
By extracting IS:  
0.23V  
IS = ------------- I FB  
R2  
Using the current sense ratio of the MOSFET GID  
0.23V  
ID = GID IS = GID ------------- I FB  
R2  
:
The current limitation is obtained with the FB pin  
shorted to ground (VFB = 0 V). This leads to a  
negative current sourced by this pin, and  
expressed by:  
0.23V  
IFB = – -------------  
R1  
By reporting this expression in the previous one, it  
is possible to obtain the drain current limitation  
START UP SEQUENCE  
IDlim  
:
This device includes a high voltage start up current  
source connected on the drain of the device. As  
soon as a voltage is applied on the input of the  
converter, this start up current source is activated  
as long as VDD is lower than VDDon. When  
reaching VDDon, the start up current source is  
switched off and the device begins to operate by  
turning on and off its main power MOSFET. As the  
FB pin does not receive any current from the  
optocoupler, the device operates at full current  
capacity and the output voltage rises until reaching

OVERVOLTAGE THRESHOLD  
An overvoltage detector on the VDD pin allows the  
VIPer22A to reset itself when VDD exceeds  
VDDovp. This is illustrated in figure 12, which shows  
the whole sequence of an overvoltage event. Note  
that this event is only latched for the time needed  
by VDD to reach VDDoff, and then the device  
resumes normal operation automatically.  
the regulation point where the secondary loop  
begins to send a current in the optocoupler. At this  
point, the converter enters a regulated operation  
where the FB pin receives the amount of current  
needed to deliver the right power on secondary  
side.  
This sequence is shown in figure 11. Note that  
during the real starting phase tss, the device  
consumes some energy from the VDD capacitor,  
waiting for the auxiliary winding to provide a  
continuous supply. If the value of this capacitor is  
too low, the start up phase is terminated before  
receiving any energy from the auxiliary winding  
and the converter never starts up. This is illustrated  
also in the same figure in dashed lines.
