ADP1877- Dual Output Synchronous Buck PWM Controller

ADP1877: Dual Output Synchronous Buck PWM Controller

The ADP1877 is a Flexmode® (proprietary architecture of Analog Devices, Inc.), dual-channel, 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 More
