UCC28713DR flyback controller 680Hz ~ 100kHz 7-SOIC
The UCC28713DR from Texas Instruments is a constant-voltage (CV) and constant-current (CC) flyback controller that leverages primary-side regulation (PSR) to eliminate the optocoupler and TL431 feedback circuitry, significantly reducing system cost and improving reliability . This device processes feedback information directly from the auxiliary flyback winding, delivering precise output regulation of ±5% across line and load variations without secondary-side components . Housed in a compact 7-pin SOIC package, the controller integrates a 700-V start-up switch and operates over a wide VDD range of 9V to 35V, supporting an industrial temperature range from -40°C to 125°C, making it ideal for compact, cost-sensitive isolated power designs .
UCC28713DR Applications
This controller is specifically designed for high-efficiency chargers and power adapters for smartphones, tablets, and portable electronics requiring USB-compliant power delivery . It is also well-suited for standby power supplies in TVs, desktop computers, and home appliances, as well as industrial power supplies demanding low standby consumption. Additional applications include LED lighting drivers where the NTC interface enables thermal foldback protection, and auxiliary power supplies for telecom and server systems requiring isolated output without optocoupler reliability concerns .
