This datasheet also covers the R2A20124AFP variant, as both devices belong to the same synchronous phase shift full-bridge controller family and are provided as variant models within a single manufacturer datasheet.
General Description
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.

ntrol IC Series Rev.3.00 Mar 11, 2011 Description 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. And RAMP slope compensation circuit is builtin as an additional function. Also its output driver circuits are improved to enlarge gate drive output voltage swing from VREF to VCC. In addition R2A20124AFP has ON/OFF function of synchronous rectificati
