说明

• Typical Application for ADP1148 Low Dropout, 3.3V/1A High Efficiency Regulator. The ADP1148 is part of a family of synchronous step-down switching regulator controllers featuring automatic sleep mode to maintain high efficiencies at low output currents. These devices drive external complementary power MOSFETs at switching frequencies up to 250 kHz using a constant off-time current-mode architecture
