†

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 UCC2800/1/2/3/4/5 family of high-speed, low-power integrated circuits contain all of the control and drive

components required for off-line and dc-to-dc fixed frequency current-mode switching power supplies with

minimal parts count.

These devices have the same pin configuration as the UC2842/3/4/5 family and also offer the added features

of internal full-cycle soft start and internal leading-edge blanking of the current-sense input.

The UCC2800/1/2/3/4/5 family offers choice of maximum duty cycle and critical voltage levels. Lower reference

parts such as the UCC2803 and UCC2805 fit best into battery operated systems, while the higher reference

and the higher UVLO hysteresis of the UCC2802 and UCC2804 make these ideal choices for use in off-line

power supplies.
