The Texas Instruments UCC2803DTR is a low-power BiCMOS current-mode PWM controller. It integrates control and drive components for off-line and DC-to-DC switching mode power supplies with minimal external parts.
Key electrical specifications include an operating voltage range of 3.6V to 12V, a maximum duty cycle of 100%, and an operating frequency up to 1MHz. It features adjustable switching frequency, current limiting, dead time control, an error amplifier, and soft start functionality. The device provides a 1A totem-pole output with a typical response time of 70ns from current-sense to gate drive output.
This controller is suitable for Boost, Flyback, and Forward converter topologies. It operates within a temperature range of -40°C to 85°C (TA).
The UCC2803DTR is available in an 8-SOIC package and is designed for surface mount applications. Its pinout is compatible with the UC3842 family.
