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 a
