UCC2813QDR-3Q1 Description

Short technical summary and product information.

The UCC2813QDR-3Q1 from Texas Instruments is an automotive-grade, low-power, BiCMOS current-mode PWM controller. It is designed for off-line and DC-to-DC fixed-frequency switching power supplies, requiring minimal external components.

 

This controller operates at up to 1MHz and features a 1.5% tolerance voltage reference. It provides a 1A totem-pole output and a fast 70ns response time from current-sense to gate-drive output. The device includes internal soft-start and leading-edge blanking of the current-sense signal.

 

Qualified for automotive applications (AEC-Q100), the UCC2813QDR-3Q1 operates within a temperature range of -40°C to 125°C. It is supplied in an 8-SOIC package suitable for surface mounting. The typical starting supply current is 100μA, and the typical operating supply current is 500μA.

 

Key electrical characteristics include a voltage range of 3.6V to 12V and a maximum duty cycle of 99%. The controller supports Boost, Flyback, and Forward Converter topologies and is not a synchronous rectifier. It offers frequency control as a key feature.
