UCC3802DTR Description

Short technical summary and product information.

The Texas Instruments UCC3802DTR is a high-speed, low-power integrated circuit designed for offline and DC-to-DC fixed frequency current-mode switching mode power supplies. It features a 1MHz operating frequency and a supply voltage range of 8.3V to 12V.

 

This PWM controller includes essential control and drive components, minimizing external part count. Key features include internal soft start, internal fault soft start, and internal leading-edge blanking of the current-sense signal. It offers a 1A totem-pole output and a typical response time of 70ns from current-sense to gate drive output.

 

The UCC3802DTR is housed in an 8-SOIC package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. The device supports various topologies including Boost, Buck, Flyback, and Forward configurations, with fault protection for current limiting.

 

This controller is pin-compatible with the UCx84x family, offering added features like internal full-cycle soft start and leading-edge blanking. It is suitable for applications requiring efficient power conversion with minimal component count.
