Description

General part information

UCC2804-EP Series

The UCC280x-Q1 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 mode power supplies with minimal parts count.

These devices have the same pin configuration as the UCx84x family, and also offer the added features of internal full-cycle soft start and internal leading-edge blanking of the current-sense input.

The UCC280x-Q1 family offers a variety of package options, temperature range options, choice of maximum duty cycle, and choice of critical voltage levels. Lower reference parts such as the UCC2803-Q1 and UCC2805-Q1 fit best into battery-operated systems, while the higher reference and higher UVLO hysteresis of the UCC2802-Q1 and UCC2804-Q1 make these ideal choices for use in off-line power supplies.
