ADP1877 Datasheet (Analog Devices) - 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 require
