The Texas Instruments UCC2813PW-1 is an economy low-power BiCMOS current-mode PWM controller. It is suitable for off-line and DC-to-DC fixed-frequency switching power supplies with minimal parts count.
Key electrical specifications include an operating voltage range of 7.4V to 12V and a maximum duty cycle of 49%. The device supports multiple topologies including Boost, Flyback, and Forward converters. It features adjustable switching frequency, current limiting, dead time control, and an error amplifier.
This controller operates within a temperature range of -40°C to 85°C. It is available in an 8-TSSOP package, designed for surface mount applications. The typical starting supply current is 100µA and operating supply current is 500µA.
The UCC2813-1 device family offers features such as internal soft start and internal leading-edge blanking of the current-sense signal, simplifying design and reducing component count.
