The LTM®4630-1A/LTM4630-1B are dual 18A or single 36A output step-down µModule® (micromodule) regulators with ±0.8% (LTM4630-1A) and ±1.5% (LTM4630-1B) total DC output error, respectively, with ±3% transient output error. Included in the package are the switching controller, power FETs,inductors,andallsupportingcomponents.Externalcompensationallowsforfasttransientresponsetominimizeoutput capacitance when powering FPGAs, ASICs, and processors. With synchronized multiphase parallel current sharing, four LTM4630-1 devices can deliver up to 144A.
