The Texas Instruments UCC38C42D is a high-performance, low-power Pulse Width Modulation (PWM) controller designed for versatile offline switching power supply applications. This 8-SOIC package component offers precise control for boost, flyback, and forward converter topologies. It features a maximum duty cycle of 96% and supports switching frequencies up to 1MHz, enabling efficient power conversion. The UCC38C42D includes an internal UVLO (Under-Voltage Lockout) circuit with a typical turn-on threshold of 10V and a hysteresis of 2V, ensuring reliable operation across its 9V to 18V supply voltage range. Its positive output configuration and single output phase are suitable for step-up and step-up/step-down DC-DC converter designs. This component finds application in various industries, including industrial power supplies and telecommunications.
