Product Introduction
The LTM4650 is a dual 25A or single 50A output switching mode step-down DC/DC µModule (power module) regulator. Included in the package are the switching controllers, power FETs, inductors, and all supporting components. Operating from an input voltage range of 4.5V to 15V, the LTM4650 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 25A continuous current for each output. Only a few input and output capacitors are needed. The LTM4650 is pin compatible with the LTM4620 (dual 13A, single 26A) and the LTM4630 (dual 18A, single 36A).
