Description
General part information
LTM4668A Series
The LTM4668A is a quad DC/DC step-down µModule (micromodule) regulator with 1.2A DC current per output. Outputs can be paralleled in an array for up to 4.8A capability. Included in the package are the switching controllers, power FETs, inductors and support components. Operating over an input voltage range of 2.7V to 17V, the LTM4668A supports an output voltage range of 0.6V to 5.5V. Only bulk input and output capacitors are needed. The device supports frequency synchronization, PolyPhase operation, selectable Burst Mode operation, 100% duty cycle and low IQoperation. Its high switching frequency and a current mode architecture enables a very fast transient response to line and load changes without sacrificing stability.Fault protection features include overvoltage, overcurrent and overtemperature protection. The power module is offered in a space saving and thermally enhanced 6.25mm × 6.25mm × 2.1mm BGA package. The LTM4668A is available with SnPb (BGA) or RoHS compliant terminal finish.ApplicationsTelecom, Networking and Industrial EquipmentMulti-Rail Point of Load RegulationFPGAs, DSPs and ASICs Application
