UCC3813D-0 Description

Short technical summary and product information.

The UCC3813D-0 from Texas Instruments is an integrated circuit designed for off-line and DC-to-DC fixed-frequency current-mode switching power supplies. This device offers a low-power, economy BiCMOS solution with a maximum operating frequency of 1MHz. It supports multiple topologies including Boost, Flyback, and Forward converters, providing flexibility for various power supply designs.

 

Key electrical characteristics include an operating voltage range of 6.9V to 12V and a maximum duty cycle of 99%. The controller features frequency control for adjustable switching frequency, along with internal soft-start and leading-edge blanking of the current-sense signal. It provides a 1A totem-pole output with a typical response time of 70ns from current-sense to gate-drive output. The typical starting supply current is 100μA, and the typical operating supply current is 500μA.

 

Packaged in an 8-SOIC surface mount configuration, the UCC3813D-0 is suitable for applications requiring a compact footprint. It operates within a temperature range of 0°C to 70°C (TA). This device is designed to minimize external component count while providing essential control and drive functions for efficient power conversion.
