DC2053A - LTM4675EY Demo Board | Dual PMBus Buck μModule Regulator, 4.5V ≤ VIN ≤ 17V, Vout0/Vout1 = 1V/1.8V @ 9A

Demonstration circuit 2053A is a dual-output, high efficiency, high density, μModule® regulator, operating from a 4.5V to 17V input range. The demo board features the LTM4675 a dual 9A or single 18A step-down regulator with PMBus digital power system management. The default dual output voltages are 1V and 1.8V, but each can be set to a voltage from 0.5V to 5.5V. Each output can supply 9A maximum load current. Please see the LTM®4675 data sheet for more detailed information.
