3 DESCRIPTIONS
The RS6651 is an internally pensated, 1.1MHz switching frequency, current mode, synchronous step-up switching regulator, which can generate 5V output at 1A load current from a 3.3V rail.
This device turns into power-saving mode to maintain high efficiency by lowering switching frequency. With its antiringing circuitry damping the charge in parasitic capacitor, it reduces EMI interference significantly. Its output is disconnected by the rectifier circuit...
