LTM4650-1 - Dual 25A or Single 50A µModule Regulator with 0.8% DC and 3% Transient Accuracy

The LTM4650-1A/LTM4650-1B is dual 25A or single 50A output step-down µModule® (power module) regulator with ±0.8% (LTM4650-1A) and ±1.5% (LTM4650-1B) total DC output error 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, six LTM4650-1 devices can deliver up to 300A. The LTM4650-1 is offered in a 16mm × 16mm × 5.01 BGA package, with SnPb (BGA) or RoHS compliant terminal finish.
