Texas Instruments UCC3803PWTR is a versatile multiphase current mode PWM controller designed for a wide range of DC-DC converter topologies, including buck, boost, flyback, and forward configurations. This device facilitates positive output step-up, step-down, and step-up/step-down voltage regulation. Key features include frequency control for precise switching frequency management up to 31kHz, and a maximum duty cycle of 99%. The UCC3803PWTR operates from a supply voltage of 3.6V to 12V and is packaged in an 8-TSSOP surface-mount format, supplied on tape and reel. Its robust design makes it suitable for applications in power supplies, industrial automation, and consumer electronics. The output type is a transistor driver, supporting a single output phase.
