Overview

Two-Phase Desktop CPU Core Supply Controllers with Controlled VID Change
General Description
The MAX1937/MAX1938/MAX1939 comprise a family of synchronous, two-phase, step-down controllers capable of delivering load currents up to 60A.
The controllers utilize Quick-PWM™ control architecture in conjunction with active load-current voltage positioning.
Quick-PWM control provides instantaneous load-step response, while programmable voltage positioning allows the converter to utilize full transient regulation limits, reducing the output capacitance requirement.
The two phases operate 180° out-of-phase with an effective 500kHz switching frequency, thus reducing input and out...
