APW7068 Overview
The fixed 300kHz switching frequency synchro- nous PWM controller drives dual N-channel MOSFETs, which provides one controlled power output with over- voltage and over-current protections. Linear controller drives an external N-channel MOSFET with under-volt- age protection. The APW7068 provides excellent regulation for output load variation.
