Enhanced Replacement for UC3842A Family  
With Pin-to-Pin Compatibility  
UCC38C4x family is a high-performance current-  
mode PWM controller. It is an enhanced BiCMOS  
version with pin-for-pin compatibility to the  
industry standard UC384xA family and UC384x  
family of PWM controllers. In addition, lower  
startup voltage versions of 7 V are offered as  
UCC38C40 and UCC38C41.

Fast 35-ns Cycle-by-Cycle Overcurrent  
Limiting  
Providing necessary features to control fixed  
frequency, peak current-mode power supplies,  
this family offers the following performance  
advantages. The device offers high-frequency  
operation up to 1 MHz with low start-up and  
operating currents, thus minimizing start-up loss  
and low operating power consumption for  
improved efficiency. The device also features a  
very fast current-sense-to-output delay time of  
35 ns and a 1 A peak output current capability  
with improved rise and fall times for driving large  
external MOSFETs directly.
