UCC28084DR Description

Short technical summary and product information.

The Texas Instruments UCC28084DR is an 8-pin SOIC package IC that functions as a DC DC switching controller. It supports both half-bridge and push-pull topologies, offering a voltage range of 4.1V to 15V and a maximum duty cycle of 49%. This controller features current limiting and frequency control, with an operating temperature range of -40°C to 85°C.

 

Key electrical characteristics include a typical run current of 1.5 mA and a low start-up current of 120 µA. The device incorporates features such as programmable slope compensation, internal soft-start, and cycle-by-cycle current limiting. It also includes a high-current totem-pole dual output stage capable of driving push-pull configurations with 1-A sink and 0.5-A source capabilities.

 

Designed for applications such as high-efficiency switch-mode power supplies, telecom dc-to-dc converters, and point-of-load power modules, the UCC28084DR is suitable for low-cost push-pull and half-bridge designs. Its surface mount package requires standard assembly processes.
