RAA220001 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...
