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 VCCis below the POR threshold. The PHASE node is connected to the gate of the low-side MOSFET (LGATE) through a 30kΩ resistor, limiting the output voltage of the converter close to the gate threshold of the low-side MOSFET. This is dependent on the current being shunted, which provides some protection to the load if the upper MOSFET(s) becomes shorted.
