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.
