Description

Demonstration circuit 2143A-C 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, andit can supply 144A maximum load current. The demoboard has four LTM®4677 µModule® regulators, and theLTM4677 is a dual 18A or single 36A step-down regulatorwith PMBus power system management. Please seeLTM4677 data sheet for more detailed informationDC2143A-C 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, Linear Technology, the Linear logo, µModule and LTpowerPlay are registeredtrademarks of Linear Technology Corporation.
