UCC28700QDBVRQ1 Description

Short technical summary and product information.

The UCC28700QDBVRQ1 from Texas Instruments is a compact primary-side regulation PWM controller designed for AC/DC switching applications. This automotive-grade device operates with a maximum switching frequency of 130 kHz and supports a wide input voltage range of 9V to 35V.

 

Key features include primary-side regulation (PSR) which eliminates the need for an opto-coupler, achieving ±5% voltage and current regulation. It also offers low standby power consumption of less than 30mW and quasi-resonant valley-switching operation for high efficiency. The controller includes essential protection functions such as overvoltage, low-line, and overcurrent protection.

 

Packaged in a SOT-23-6 surface-mount package, the UCC28700QDBVRQ1 is suitable for designs requiring a small footprint. Its automotive qualification (AEC-Q100 Grade 1) and functional safety capability make it a robust choice for demanding applications.

 

This device is ideal for flyback topologies and offers features like green mode, soft start, and programmable cable compensation, contributing to ease of EMI compliance and overall system performance.
