说明
- ADP1877 is a current mode dual-phase step-down switching controller with integrated drivers that drive N-channel synchronous power MOSFETs. The two PWM outputs are phase shifted 180, which reduces the input RMS current thus minimizing required input capacitance. The boost diodes are built into the ADP1877, thus lowering the overall system cost and component count. The ADP1877 can be set to operate in pulse skip high efficiency mode under light load or in forced PWM (continuous conduction mode)
