GENERAL DESCRIPTION

The ADP2325 is a full featured, dual output, step-down dc-to-dc regulator based on a current mode architecture. The ADP2325 integrates two high-side power MOSFETs and two low-side drivers for the external N-channel MOSFETs. The two pulse-width modulation (PWM) channels can be configured to deliver dual 5 A outputs or a parallel-to-single 10 A output. The regulator operates from input voltages of 4.5 V to 20 V, and the output voltage can be as low as 0.6 V.
