UCC3801 Description

Short technical summary and product information.

The Texas Instruments UCC3801 is a high-speed, low-power BiCMOS current-mode PWM controller. It is suitable for off-line and DC-to-DC fixed frequency switching mode power supplies.

 

Key electrical specifications include an operating frequency of up to 1MHz, a maximum duty cycle of 50%, and an output current capability of 1A. It features adjustable switching frequency, current limiting, dead time control, an error amplifier, fixed frequency operation, leading-edge blanking, multi-topology support, and soft start functionality. The device also has a typical starting supply current of 100μA and an operating supply current of 500μA.

 

The UCC3801 operates within a temperature range of 0°C to 70°C. It is available in SOIC and TSSOP 8-pin packages. The pin configuration is similar to the UC3842 and UC3842A families, offering internal full-cycle soft start and leading-edge blanking of the current-sense input.

 

This controller is designed for applications requiring efficient power conversion with minimal external components. Its features make it adaptable to various power supply topologies including Boost and Flyback.
