DESCRIPTION
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.Externalcom-
pensationallowsforfasttransientresponsetominimizeoutput
capacitance when powering FPGAs, ASICs, and processors.
With synchronized multiphase parallel current sharing, four
LTM4630-1 devices can deliver up to 144A. The LTM4630-1
is offered in a 16mm × 16mm × 5.01 BGA package.
