XRP7725 Intel Node Manager Compatible Programmable Power Management System January 2014 Rev. 1.0.0 GENERAL DESCRIPTION The XRP7725 is a quad channel Digital Pulse Width Modulated (DPWM) Step down (buck) controller. A wide 4.75V to 5.5V and 5.5V to 25V input voltage dual range allows for single supply operation from standard power rails. With integrated FET gate drivers, two LDOs for standby power and a 105kHz to 1.23MHz independent channel to channel programmable constant operating frequency, the XRP7725 reduces overall component count and solution footprint and optimizes conversion efficiencies.
