UCC28722DBVR Description

Short technical summary and product information.

The UCC28722DBVR from Texas Instruments is a flyback power supply controller designed for isolated-output constant-voltage (CV) and constant-current (CC) regulation. It utilizes primary-side regulation (PSR) to eliminate the need for an optical coupler, simplifying the design and reducing component count.

 

This controller operates within a wide input voltage range of 9V to 35V and features a maximum switching frequency of 80kHz, enabling high-power density charger designs. It provides precise control of output voltage and current with tight regulation of ±5% across varying line and load conditions. The device also includes essential protection functions such as output overvoltage, low-line, and overcurrent protection.

 

Packaged in a compact SOT-23-6 surface-mount package, the UCC28722DBVR is suitable for applications requiring efficient and reliable power conversion. Its operating temperature range is -40°C to 125°C (TJ). The controller supports quasi-resonant valley-switching operation for enhanced overall efficiency and achieves less than 50mW of no-load power consumption.
