The Texas Instruments UCC28C42DR is a high-performance, low-power current-mode PWM controller. It is designed for various topologies including Boost, Buck, Flyback, and Forward converters.
This controller features an operating voltage range of 9V to 18V and a maximum duty cycle of 96%. It supports adjustable switching frequencies up to 1MHz and includes essential control features such as current limiting and an error amplifier. The device also incorporates undervoltage lockout protection with 14.5V/9V thresholds.
Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, the UCC28C42DR is suitable for applications requiring compact designs. It offers fast cycle-by-cycle overcurrent limiting with a response time of 35ns and provides a peak driving current of ±1A.
This controller is an enhanced replacement for the UCx84x and UCx84xA families, offering improved performance and efficiency for power supply designs.
