UCC2802-Q1 PWM

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.
