R2A20124AFP Overview
The R2A20124AFP/R2A20124ASP controls a full-bridge phase shift circuit and secondary synchronous rectification. The R2A20124AFP/R2A20124ASP has adjustable delay time functions which make ZVS of primary side and make loss of body diode of primary switching device minimal. The R2A20124AFP/R2A20124ASP is based on HA16163/R2A20121.
