Quality Control: Learn More
The Texas Instruments UCC28C42DGK is a high-performance, fixed-frequency, current-mode PWM controller designed for off-line power supplies. This versatile component supports Boost, Flyback, and Forward converter topologies for positive output voltage regulation. Featuring integrated UVLO (Under-Voltage Lockout) with a 9V to 18V operating range and a maximum duty cycle of 96%, it is optimized for efficient power conversion up to 1MHz switching frequencies. The UCC28C42DGK is packaged in an 8-VSSOP (8-TSSOP, 8-MSOP) surface-mount configuration, making it suitable for compact designs. Its applications span across various industries including industrial automation, consumer electronics, and telecommunications equipment. The device offers precise frequency control and is designed for single-phase output configurations.
