UCC3801D Description

Short technical summary and product information.

The Texas Instruments UCC3801D is a high-speed, low-power BiCMOS current-mode PWM controller. It integrates essential control and drive components for off-line and DC-to-DC fixed frequency switching mode power supplies.

 

This controller supports multiple topologies including Buck, Boost, Flyback, and Forward converters. It features an adjustable switching frequency up to 1MHz, with a maximum duty cycle of 49%. Key electrical characteristics include a voltage range of 7.4V to 12V and a typical operating supply current of 500µA.

 

The UCC3801D is housed in an 8-SOIC package, suitable for surface mount applications. It operates within a temperature range of 0°C to 70°C. The device offers features such as frequency control, current limiting, and internal soft start.

 

This part is pin-compatible with the UCx84x family and offers added features like internal full-cycle soft start and leading-edge blanking of the current-sense input.
