UCC2813D5 Description

Short technical summary and product information.

The Texas Instruments UCC2813D-5 is an integrated circuit that provides control and drive components for fixed-frequency, current-mode switching power supplies. This device is designed for both off-line and DC-to-DC applications, requiring minimal external components.

 

Key electrical specifications include a maximum operating frequency of 1000 kHz, a typical gate drive current of 1A, and a low operating supply current of 500 µA. It features internal soft start, internal fault soft start, and internal leading-edge blanking of the current-sense signal. The voltage reference has a tolerance of 1.5%.

 

The UCC2813D-5 supports multiple topologies including Boost, Flyback, and Forward. It operates within a wide input voltage range from 4.1V to 400V and has UVLO thresholds set at 4.1V (on) and 3.6V (off). The typical response time from current-sense to gate-drive output is 70 ns.

 

Packaged in an 8-pin SOIC, this component is suitable for surface mounting. It operates within a temperature range of -40°C to 85°C. The device is RoHS3 compliant and has an MSL rating of 1.
