Description

The LTM®4650-2 is a dual 25A or single 50A output stepdown μModule®(micromodule) regulator with ±1.5% total DC output error. The package includes 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. AVP can further improve transient response and reduce the output capacitance. With synchronized multiphase parallel current sharing, six LTM4650-2 devices can deliver up to 300A.The LTM4650-2 is offered in a 16mm × 16mm × 5.01mm BGA package with SnPb or RoHS-compliant terminal finish.APPLICATIONSFPGA, ASIC, μProcessor Core Voltage RegulationInformation, Communication Systems
