n Industrial Equipment The LTM®4631 is a dual 10A or single 20A output switching mode step-down DC/DC µModule® (power module)
regulator. Included in the package are the switching controller, power FETs, inductors and all supporting components. Operating from an input voltage range of 4.5V to
15V, the LTM4631 supports two outputs each with an
output voltage range of 0.6V to 1.8V, each set by a single
external resistor. Its high efficiency design delivers up to …
