UCC28C41DR Description

Short technical summary and product information.

The UCC28C41DR from Texas Instruments is a high-performance, low-power current-mode PWM controller. It is suitable for Boost, Buck, Flyback, and Forward converter topologies. This controller operates at frequencies up to 1MHz and features a maximum duty cycle of 48%.

 

Key electrical characteristics include a voltage range of 6.6V to 18V and an operating temperature range of -40°C to 105°C. It offers fast, cycle-by-cycle overcurrent limiting with a response time of 35ns and a peak driving current of ±1A. The device also includes features like adjustable switching frequency, dead time control, and an error amplifier with a ±1% accurate 2.5V reference.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, the UCC28C41DR is designed for efficient power management applications. It serves as an enhanced replacement for the UCx84x and UCx84xA families, offering pin-to-pin compatibility and improved performance characteristics.
