Description

Demonstration circuit 2143A-A 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 72A maximum load current. The demo boardhas two LTM®4677 µModule regulators, and the LTM4677is a dual 18A or single 36A step-down regulator withPMBus power system management. Please see LTM4677data sheet for more detailed informationDC2143A-A 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 useLTC’s I2C/SMBus/PMBus dongle DC1613A to connect toL, LT, LTC, LTM, Linear Technology, the Linear logo and µModule are registered trademarksand LTpowerPlay is a trademark of Linear Technology Corporation.
