Categories: DC DC Switching Controllers
Quality Control: Learn More
The Texas Instruments UCC28C42P is a high-performance, fixed-frequency current-mode PWM controller designed for offline and DC-DC converter applications. This device features a voltage feed-forward function, enabling it to maintain constant switching frequency and manage output voltage over wide input voltage variations. Optimized for Boost, Flyback, and Forward converter topologies, it provides a positive output, driving a single output phase. The UCC28C42P operates with a switching frequency of up to 1MHz and offers a maximum duty cycle of 96%. Its integrated UVLO circuitry ensures operation within a supply voltage range of 9V to 18V. The controller is housed in an 8-PDIP package suitable for through-hole mounting and operates across an industrial temperature range of -40°C to 105°C. It finds application in power supply designs for industrial equipment and consumer electronics.
