RAA220002 Overview
Datasheet RAA220002 Dual Synchronous Rectified Buck MOSFET Driver The RAA220002 is a dual high frequency MOSFET driver designed to drive upper and lower power N-channel MOSFETs in a synchronous rectified buck converter topology. The RAA220002’s upper and lower gates are both driven to an externally applied voltage, which provides the ability to optimize applications involving trade-offs between gate charge and conduction losses. An advanced adaptive shoot-through protection is integrated to prevent both the upper and lower MOSFETs from conducting simultaneously and to minimize dead time. The RAA220002 has a 10kΩ integrated high-side gate-to-source resistor to prevent self turn-on due to high input bus dV/dt. The RAA220002’s overvoltage protection feature is operational while VCC is below the POR threshold. The PHASE node is connected to the gate of the low-side MOSFET (LGATE) through a...
