UCC2813-0-Q1 - Texas Instruments

UCC2813-0-Q1 Low-Power Economy BiCMOS PWM

The UCC2813-x-Q1 device family of high-speed, lowpower integrated circuits contains all of the control and drive components required for off-line and DC-toDC fixed-frequency current-mode switching power supplies with minimal parts count. These devices have the same pin configuration as the UC284x device family, and also offer the added features of internal f.
