UCC28C43DGKR Description

Short technical summary and product information.

The Texas Instruments UCC28C43DGKR is a low-power, current-mode Pulse Width Modulation (PWM) controller designed for AC/DC and DC/DC power conversion applications. It supports multiple topologies including Boost, Buck, Flyback, and Forward converters.

 

Key electrical specifications include an operating voltage range of 7.6V to 18V, a maximum duty cycle of 96%, and an operating frequency of up to 1MHz. The device features fast, cycle-by-cycle overcurrent limiting with a response time of 35ns and a peak driving current of ±1A. It also includes an accurate 2.5V error amplifier reference and undervoltage lockout protections.

 

The UCC28C43DGKR is available in an 8-VSSOP package, suitable for surface mount applications. Its compact package size and low operating current make it a versatile choice for various power management designs. This controller is an enhanced replacement for the UCx84x and UCx84xA families, offering pin-to-pin compatibility with upgraded functionality.

 

This component is designed for industrial applications requiring efficient and reliable power control. Its features enable the design of compact and high-performance power supplies.
