UCC3807DTR-1 Description

Short technical summary and product information.

The Texas Instruments UCC3807DTR-1 is a high-speed, low-power integrated circuit that provides control and drive circuitry for fixed-frequency current-mode switching power supplies. It is suitable for both off-line and DC-to-DC applications, requiring minimal external components.

 

Key features include a user-programmable maximum duty cycle of 78% and an operating frequency of 202kHz. The device supports a wide supply voltage range of 6.9V to 13.5V and offers a 1A totem pole output. It also incorporates internal full-cycle soft start and leading-edge blanking for the current sense signal.

 

This controller is designed for various topologies including Buck, Boost, Flyback, Forward Converter, and SEPIC. It is housed in an 8-SOIC package suitable for surface mounting and operates within a temperature range of 0°C to 70°C.

 

The UCC3807DTR-1 is an efficient solution for power supply designs where precise control over duty cycle and frequency is required.
