UCC28881DR
Brand: Texas Instruments
The UCC28881DR is a single-chip off-line converter that operates directly from rectified AC mains through an integrated 700 V, 14 Ω MOSFET, supporting buck, buck-boost or flyback topologies without a separate high-voltage startup circuit. Internal soft start, current limit and overtemperature protection in a 7-pin SOIC make it a compact solution for off-line auxiliary and metering power supplies.
