The NCP81232 can be configured as a single or dual output regulator intended to operate with DrMOS power stages. This IC can be set with up to 8 unique output configurations that offer the operate as a single output with operation from a single to quad phases or as a dual output device with phase combinations of 3+1, 2+2, 2+1, and 1+1. This controller offers differential current sense and voltage sense for greater accuracy. The device supports DCR current sense or can accommodate an IMON signal from the DrMOS. The parts offer protection against overcurrent, over/undervoltage, and overtemperature protection.
