DESCRIPTION  
The UCC28C4x family are high performance current-mode PWM controllers. They are enhanced BiCMOS  
versions with pin-for-pin compatibility to the industry standard UC284xA family and UC284x family of PWM  
controllers. In addition, a lower startup voltage versions of 7 V is offered as UCC28C41.  
Providing necessary features to control fixed frequency, peak current mode power supplies, this family offers  
several performance advantages. These devices offer 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 devices also feature a 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.  
The UCC28C4x family is offered in the 8-pin SOIC (D) package.
