ADP1850DP-EVALZ

ADP1850DP-EVALZ is an evaluation board for the ADP1850DP step-down DC-to-DC controller operating in dual-phase mode. The ADP1850 is a dual-channel, step-down switching controller with integrated drivers for external N-channel synchronous power MOSFETs. The two PWM outputs are phase shifted 180°, which reduces the input RMS ripple current, thus minimizing required input capacitance. The two outputs can be combined for dual-phase PWM operation that can deliver more than 50A output current. The internal parameters of the two channels are optimized for current sharing. In addition, boost diodes are integrated into the ADP1850, thus lowering the overall system cost and component count. The ADP1850 can be set to operate in pulse skip, high efficiency mode under light load or in PWM continuous conduction mode.
