Multi-Phase Controller with Dual Loop Capability, Configurable, DrMOS Compatible

Favorite

Overview

The NCP81234 can be configured as a single or dual output regulator intended to operate with DrMOS power stages. The device operates from 4.5V to 24V and is ideally suited for powering processors, DDR memory, and FPGAs. The device offers dual control loops, allowing independent operation of each loop with the ability to parallel the outputs for a higher 2 phase solution. 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.
