Beschreibung
Demonstration circuit 2481A-B is a high efficiency, highdensity, µModule® regulator with 4.5V to 16V input range.The output voltage is adjustable from 0.5V to 1.8V, and itcan supply 186A maximum load current. The demo boardhas 1× LTM®4677 and 3× LTM4650 µModule regulators.The LTM4677 is a dual 18A or single 36A step-downregulator with PMBus power system management, and theLTM4650 is a dual 25A or single 50A step-down regulator.Please see LTM4677 and LTM4650 data sheets for moredetailed information.DC2481A-B powers up to default settings and producepower based on configuration resistors without the needfor any serial bus communication. This allows easy evaluationof the DC/DC converter. To fully explore the extensivepower system management features of the part, downloadthe GUI software LTpowerPlay® onto your PC and useL, LT, LTC, LTM, µModule, LTpowerPlay, Linear Technology and the Linear logo are registeredtrademarks of Linear Technology Corporation.
