DC2481A-B - LTM4677/LTM4650 Demo Board | Buck μModule Regulator with Digital PSM, LTM4677 + LTM4650(x3), 4.5V ≤ VIN ≤ 16V, Vout = 0.5V to 1.8V @ 186A

Demonstration circuit 2481A-B is a high efficiency, high density, μModule® regulator with 4.5V to 16V input range. The output voltage is adjustable from 0.5V to 1.8V, and it can supply 186A maximum load current. The demo board has 1× LTM®4677 and 3× LTM4650 μModule regulators. The LTM4677 is a dual 18A or single 36A step-down regulator with PMBus power system management, and the LTM4650 is a dual 25A or single 50A step-down regulator. Please see LTM4677 and LTM4650 data sheets for more detailed information.
