Analog Devices' LTC3376 is part of the LTC337x configurable, multi-output, eight power stage, buck regulator family. The LTC3376 devices extend the maximum input voltage from 5.5 V to 20 V making them ideal for industrial and 12 V/18 V adapter applications. These regulators provide 15-pin selectable-output configurations (1.5 A to 12 A per channel), a wide input voltage range of 3 V to 20 V, a wide output voltage of 0.4 V to 0.83 VIN, and internal boost capacitors for reduced PCB space.
