RAA212831 4.5V to 72V Input, 0.5A Buck Regulator with Two Linear Regulator Outputs Datasheet The RAA212831 is a triple output regulator combining 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 LDOs operate from a 12V (or lower) input voltage. The LDOs are rated at 100mA and 50mA of output current. The buck regulator output can be set from 1.25V to VIN×Dmax. The LDOs can support an input voltage range of 6V to 12V and the output voltages are fixed at 3.3V and 5V. The IC is designed to provide a compact, highly integrated power management solution.
