KA3825  
SMPS CONTROLLER  
HIGH SPEED PWM CONTROLLER  
16-DIP  
The KA3825 is a high speed PWM controller for high fre-  
quency SMPS applications. This controller includes prec-  
ise voltage reference, low start up current circuit, soft st-  
art, high frequency oscillator, high speed Current limit co-  
mparator, wideband error amplifier, double pulse suppre-  
sion logic, and double totempole output drivers. Circuit  
design for high speed and schottky process result in very  
short propagation delays through the current limit compa-  
rator, logic and output drivers. Also KA3825 is available  
for both current mode and voltage mode power supply.  
FEATURES  
Precision Voltage Reference  
Wide Bandwidth Error Amplifier  
50ns Propagation Delay to Output  
Under Voltage Lock Out with Hysteresis  
Soft Start and Max. Duty Cycle Control  
Low Start Up Current  
Double Pulse Suppression Logic
