Typical Application
Description
The LTM®4630-1A/LTM4630-1B are dual 18A or single 36A output step-down μModule® (power module) 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, and all supporting components. External compensation allows for fast transient response to minimize output 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.
