Overview
The LTM4631EV#PBF is a high-efficiency, dual 10A or single 20A output switching mode step-down DC/DC µModule (power module) regulator produced by Linear Technology. This ultrathin module integrates the switching controller, power FETs, inductors, and all supporting components into a single package. It operates from an input voltage range of 4.5V to 15V and supports two outputs, each with an output voltage range of 0.6V to 1.8V, set by a single external resistor. The module is designed for high efficiency and requires only a few input and output capacitors for operation.
