(1) Component qualification in accordance with JEDEC and  
industry standards to ensure reliable operation over an  
extended temperature range. This includes, but is not limited  
to, Highly Accelerated Stress Test (HAST) or biased 85/85,  
temperature cycle, autoclave or unbiased HAST,  
electromigration, bond intermetallic life, and mold compound  
life. Such qualification testing should not be viewed as  
justifying use of this component beyond specified  
performance and environmental limits.  
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, lower startup voltage versions of 7 V are offered as UCC28C40 and 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 8-pin package SOIC (D).
