Texas Instruments UCC28C42D is an 8-SOIC offline PWM controller designed for high-performance DC-DC conversion. This component facilitates Boost, Flyback, and Forward converter topologies, supporting step-up and step-up/step-down output configurations. Featuring frequency control and a maximum duty cycle of 96%, the UCC28C42D operates with switching frequencies up to 1MHz. Its integrated UVLO (Under-Voltage Lockout) ensures reliable startup, and it includes a single output driver. The device operates within a voltage supply range of 9V to 18V and a junction temperature range of -40°C to 105°C. This controller is suitable for applications in power supplies, industrial automation, and consumer electronics.
