DESCRIPTION  
(1)  
Qualification Pedigree  
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.  
Enhanced Replacements for UC2842A Family  
With Pin-to-Pin Compatibility

•
1-MHz Operation  
50-µA Standby Current, 100-µA Maximum  
Low Operating Current of 2.3 mA at 52 kHz  
Fast 35-ns Cycle-by-Cycle Overcurrent  
Limiting  
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.  
•
•
±1-A Peak Output Current  
Rail-to-Rail Output Swings With 25-ns Rise  
and 20-ns Fall Times  
•
±1% Initial Trimmed 2.5-V Error Amplifier  
Reference  
(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.  
The UCC28C4x family is offered in 8-pin package  
SOIC (D).
