The Texas Instruments UCC3801PW is a versatile, high-performance PWM controller designed for a wide range of DC-DC converter topologies including Buck, Boost, Flyback, and Forward. This device features a positive output configuration with a single output phase and operates as a transistor driver. Its control capabilities include frequency control, with a maximum duty cycle of 49% and a switching frequency of 46kHz. The UCC3801PW supports step-up, step-down, and step-up/step-down functions. It is packaged in an 8-TSSOP (0.173", 4.40mm width) surface mount configuration. Operating within a supply voltage range of 7.4V to 12V, this controller is suitable for applications in power supplies, industrial controls, and consumer electronics. The operating temperature range is 0°C to 70°C (TA).
