Description

The LTM4671 is a quad DC/DC step-down µModule (micromodule) regulator offering dual 12A and dual 5A output. Included in the package are the switching controllers, power FETs, inductors and support components. Operating over an input voltage range of 3.1V to 20V, the LTM4671 supports an output voltage range of 0.6V to 3.3V for two 12A channels and 0.6V to 5.5V for two 5A channels, each set by a single external resistor. Only bulk input and output capacitors are needed.
