UCC28C45DGKR Description

Short technical summary and product information.

The Texas Instruments UCC28C45DGKR is a low-power, current-mode PWM controller. It is suitable for multiple topologies including Boost, Flyback, and Forward converters. This device operates with a voltage range of 7.6V to 18V and supports adjustable switching frequencies up to 1MHz.

 

Key electrical features include a maximum duty cycle of 48%, fast cycle-by-cycle overcurrent limiting with a 35ns response time, and a peak driving current of ±1A. It also incorporates an accurate 2.5V error amplifier reference with ±1% accuracy and undervoltage lockout protections.

 

The UCC28C45DGKR is available in an 8-VSSOP package, offering a compact solution with a package size of 14.7 mm². It is designed for surface mount applications and operates within a temperature range of -40°C to 105°C (TJ).

 

This controller serves as an enhanced replacement for the UCx84x and UCx84xA families, offering improved performance characteristics such as lower startup and operating currents, and better efficiency.
