DESCRIPTION
●TheLTM®4630is a dual 18A or single 36A output switching mode step-down DC/DC µModule®(micromodule) 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 LTM4630 supports two outputs each with an output voltage range of 0.6V to 1.8V, each set by a single external resistor. Its high effciency design delivers up to 18A continuous current for each output. Only a few input and output capacitors are needed. The LTM4630 is pin compatible with the LTM4620 and LTM4620A (dual 13A, single 26A) and the LTM4628 (dual 8A, single 16A).
