Overview

XR77129 40V Quad Output Digital PWM/PFM Universal PMIC General Description The XR77129 is a quad channel digital Pulse Width Modulated (PWM) step down (buck) controller.
A wide 6V to 40V input voltage 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 XR77129 reduces overall component count, solution footprint and optimizes conversion efficiencies.
A selectable digital Pulse Frequency Mode (PFM) capable of better than 80% efficiency at light current load and low operating current allow for portable and Energy Star...
