产品型号UCC3801N的概述

UCC3801N芯片概述 UCC3801N是一款高效、集成的DC-DC转换器控制芯片,特别适合用于高频开关模式电源(SMPS)应用。其主要特点是具备高精度的电流模式控制,这使其在调节输出电压和电流方面具有优良的表现。由于其设计的灵活性和强大的功能,UCC3801N被广泛应用于消费电子、工业电源及通信设备中。 该芯片采用了先进的PWM(脉宽调制)控制技术,能够在不同的负载条件下保持稳定的输出,同时提高系统的效率。UCC3801N还具有多种保护功能,如过流保护、过温保护以及欠压锁定等,能够有效保证整个电源系统的安全性和可靠性。 UCC3801N的详细参数 | 参数 | 说明 | |---------------------|------------------------| | 工作电压范围 | 4.5...

Low-Power BiCMOS Current-Mode PWM  
FEATURES  
DESCRIPTION  
100µA Typical Starting Supply Current  
The UCC1800/1/2/3/4/5 family of high-speed, low-power integrated cir-  
cuits contain all of the control and drive components required for off-line  
and DC-to-DC fixed frequency current-mode switching power supplies  
with minimal parts count.  
500µA Typical Operating Supply  
Current  
Operation to 1MHz  
Internal Soft Start  
These devices have the same pin configuration as the UC1842/3/4/5  
family, and also offer the added features of internal full-cycle soft start  
and internal leading-edge blanking of the current-sense input.  
Internal Fault Soft Start  
The UCC1800/1/2/3/4/5 family offers a variety of package options, tem-  
perature range options, choice of maximum duty cycle, and choice of  
critical voltage levels. Lower reference parts such as the UCC1803 and  
UCC1805 fit best into battery operated systems, while the higher refer-  
ence and the higher UVLO hysteresis of the UCC1802 and UCC1804  
make these ideal choices for use in off-line power supplies.  
The UCC180x series is specified for operation from –55oC to +125oC,  
the UCC280x series is specified for operation from –40oC to +85oC, and  
the UCC380x series is specified for operation from 0oC to +70oC.

Current Sense Signal

short and direct as possible. If possible, use separate  
ground traces for the timing capacitor and all other func-  
tions.

family is a true, low output-impedance, 2MHz operational  
amplifier. As such, the COMP terminal can both source The frequency of oscillation can be estimated with the

where frequency is in Hz, resistance is in ohms, and ca-  
pacitance is in farads. The recommended range of timing  
resistors is between 10k and 200k and timing capacitor is  
100pF to 1000pF. Never use a timing resistor less than  
10k.  
CS: CS is the input to the current sense comparators.  
The UCC3800 family has two different current sense  
comparators: the PWM comparator and an over-current  
comparator.  
The UCC3800 family contains digital current sense filter-  
ing, which disconnects the CS terminal from the current  
sense comparator during the 100ns interval immediately  
following the rising edge of the OUT pin. This digital filter-  
ing, also called leading-edge blanking, means that in  
most applications, no analog filtering (RC filter) is re-  
quired on CS. Compared to an external RC filter tech-  
nique, the leading-edge blanking provides a smaller  
effective CS to OUT propagation delay. Note, however,  
that the minimum non-zero On-Time of the OUT signal is  
directly affected by the leading-edge-blanking and the CS  
to OUT propagation delay.  
To prevent noise problems, bypass VCC to GND with a  
ceramic capacitor as close to the VCC pin as possible.  
An electrolytic capacitor may also be used in addition to  
the ceramic capacitor.  
REF: REF is the voltage reference for the error amplifier  
and also for many other functions on the IC. REF is also  
used as the logic power supply for high speed switching  
logic on the IC.  
When VCC is greater than 1V and less than the UVLO  
threshold, REF is pulled to ground through a 5k ohm re-  
sistor. This means that REF can be used as a logic out-  
put indicating power system status. It is important for  
reference stability that REF is bypassed to GND with a  
ceramic capacitor as close to the pin as possible. An  
electrolytic capacitor may also be used in addition to the  
ceramic capacitor. A minimum of 0.1µF ceramic is re-  
quired. Additional REF bypassing is required for external  
loads greater than 2.5mA on the reference.  
The over-current comparator is only intended for fault  
sensing, and exceeding the over-current threshold will  
cause a soft start cycle.  
FB: FB is the inverting input of the error amplifier. For  
best stability, keep FB lead length as short as possible  
and FB stray capacitance as small as possible.  
GND: GND is reference ground and power ground for all  
To prevent noise problems with high speed switching  
transients, bypass REF to ground with a ceramic capaci-  
tor very close to the IC package.  
functions on this part.  
OUT: OUT is the output of a high-current power driver ca-  
pable of driving the gate of a power MOSFET with peak  
currents exceeding ± 750mA. OUT is actively held low  
when VCC is below the UVLO threshold.  
VCC: VCC is the power input connection for this device.  
In normal operation VCC is powered through a current  
limiting resistor. Although quiescent VCC current is very  
low, total supply current will be higher, depending on  
OUT current. Total VCC current is the sum of quiescent  
VCC current and the average OUT current. Knowing the  
operating frequency and the MOSFET gate charge (Qg),  
average OUT current can be calculated from:  
The high-current power driver consists of FET output de-  
vices, which can switch all of the way to GND and all of  
the way to VCC. The output stage also provides a very  
low impedance to overshoot and undershoot. This means  
that in many cases, external schottky clamp diodes are  
not required.  
IOUT = Qg × F.  
RC: RC is the oscillator timing pin. For fixed frequency  
operation, set timing capacitor charging current by con-  
necting a resistor from REF to RC. Set frequency by con-  
necting a timing capacitor from RC to GND. For best  
There should be a minimum of 1.0mF in parallel with a  
0.1mF ceramic capacitor from VCC to ground located  
close to the device

UCC2800/1/2/3/4/5  
UCC3800/1/2/3/4/5  
The UCC3800/1/2/3/4/5 oscillator generates a sawtooth  
waveform on RC. The rise time is set by the time constant  
of RT and CT. The fall time is set by CT and an internal tran-  
sistor on-resistance of approximately 125 . During the fall  
time, the output is off and the maximum duty cycle is re-  
duced below 50% or 100% depending on the part number.  
Larger timing capacitors increase the discharge time and re-  
duce the maximum duty cycle and frequency.

Eco Plan  
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS  
&
no Sb/Br)  
-
please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
