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.
