RAA212831 Overview
RAA212831 4.5V to 72V Input, 0.5A Buck Regulator with Two Linear Regulator Outputs Datasheet The RAA212831 is a triple output regulator bining a 4.5V to 72V input, 0.5A buck regulator with two LDO outputs. The buck regulator has a fixed switching frequency of 350kHz in Continuous Conduction mode (CCM) and operates in pulse skipping mode at lighter loads when it enters Discontinuous Conduction mode (DCM). The two...
