UCC2804QDRQ1 Description

Short technical summary and product information.

The Texas Instruments UCC2804QDRQ1 is a high-speed, low-power, automotive-grade PWM controller designed for offline and DC/DC fixed-frequency current mode switching power supplies. It operates at frequencies up to 1MHz with a 50% duty cycle and supports an operating voltage range of 8.3V to 12V.

 

This controller integrates essential control and drive components, requiring minimal external parts. Key features include internal soft-start, internal leading-edge blanking on the current sense input, and a 1A totem pole output. The device is suitable for applications requiring current limiting fault protection.

 

Packaged in an 8-SOIC surface-mount package, the UCC2804QDRQ1 operates within an ambient temperature range of -40°C to 125°C. It is designed for automotive applications and meets AEC-Q100 standards.

 

This controller is ideal for building efficient power supplies where precise control and robust protection are necessary. Its pin configuration is compatible with UC3842 and UC3842A series.
