The LTM4660 is a complete 300W output switching mode hybrid-topology step-down DC/DC μModule®(micromodule) nonisolated bus converter. Its exposed power inductor resides on the top of the package, providing an intrinsic path for heat to dissipate up and out of the module—away from one’s printed circuit board. Included in the package are the switching controller IC, power MOSFETs and supporting components. Only flying (charge-pump) capacitors, bulk input and output bypass capacitors, and a few configuration passives are needed.The LTM4660 features frequency synchronization, Burst Mode®operation and output voltage soft-start and tracking. An onboard temperature diode is available for temperature monitoring. The LTM4660 protects against short-circuit, overcurrent, and overtemperature faults. For higher power applications, multiple LTM4660 modules can be easily paralleled.The LTM4660 is offered in a 16mm × 16mm × 10.34mm BGA package with RoHS compliant terminal finish.APPLICATIONSTelecom, Data Centers and Networking EquipmentIndustrial and Test Equipment
