General Description
The APW7004 provides a complete control and multiple protection for a DC-DC converter optimized for high performance microprocessor applications. It is designed to drive two N-Channel MOSFETs in a synchronous-rectified buck topology. The APW7004 integrates output voltage control, output voltage programming, monitoring and protection functions into a single chip IC.
