Texas Instruments UCC28910 series AC to DC Converter ICs

The UCC28910 and UCC28911 are high-voltage flyback switchers that provide output voltage and current regulation without the use of an optical coupler. Both devices incorporate a 700-V power FET and a controller that process operating information from the flyback auxiliary winding and power FET to provide a precise output voltage and current control. The UCC28910 series offers constant-voltage (CV) and constant-current (CC) output regulation without an optical coupler, ±5% output voltage regulation accuracy, ±5% output current regulation with AC line and primary inductance tolerance compensation, 700 V start-up and smart power management enable best-in-class <30 mW standby power.
