HIP6603A Synchronous Rectified Buck MOSFET Drivers

UGATE (Pin 1), (Pin 16 QFN) Upper gate drive output. Connect to gate of high-side power N-Channel MOSFET. BOOT (Pin 2), (Pin 2 QFN) Floating bootstrap supply pin for the upper gate drive. Connect the bootstrap capacitor between this pin and the PHASE pin. The bootstrap capacitor provides the charge to turn on the upper MOSFET. A resistor in series with boot .
