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.
