Overview
Datasheet RAA220001 Synchronous Rectified Buck MOSFET Driver The RAA220001 is a high frequency MOSFET driver designed to drive upper and lower power N-channel MOSFETs in a synchronous rectified buck converter topology.
In the RAA220001, the upper and lower gates are both driven to an externally applied voltage that provides the capability 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 RAA220001 has a 10kΩ integrated high-side gate-to-source resistor to prevent self turn-on due to high input bus dV/dt.
This driver also has an overvoltage protection feature that 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 30kΩ resistor, limiting the output voltage of the converter close to the gate threshold o...
