Quality Control: Learn More
Texas Instruments UCC38C44D is a high-performance, versatile PWM Current Mode Controller. This device is engineered for off-line power supplies and DC-DC converters, supporting Boost, Flyback, and Forward converter topologies. It features a fixed-frequency architecture with operational frequencies up to 1MHz, and a maximum duty cycle of 48%. Integrated UVLO (Under-Voltage Lockout) ensures reliable startup and operation within a supply voltage range of 9V to 18V. The UCC38C44D provides a positive output configuration and is packaged in an 8-SOIC surface-mount case. This controller is well-suited for applications in consumer electronics, industrial power, and telecommunications.
