RT9619/A Synchronous-Rectified Buck MOSFET Drivers General Description The RT9619/A is a high frequency, dual MOSFET driver specifically designed to drive two power N-Channel MOSFETs in a synchronous-rectified buck converter topology. This driver combined with Richtek's series of Multi-Phase Buck PWM controller form a complete corevoltage regulator solution for advanced micro-processors. www.DataSheet4U.com The RT9619/A drives both the lower/upper gate in a synchronous-rectifier bridge with 12V. This drive-voltage flexibility provides the advantage of optimizing applications involving trade-offs between switching losses and conduction losses. RT9619A has longer UGATE/LGATE deadtime which can drive the MOSFETs with large gate RC value, avoiding the shoot-through phenomenon.
