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. Its integrated buck regulator and LDO outputs minimize system component count.
