DC2479A-A - LTM4650EY Demo Board | Dual Phase Buck μModule Regulator, 4.5V ≤ VIN ≤ 15V, Vout = 0.6V to 1.8V @ 50A

Demonstration circuit 2479A-A features the LTM®4650EY, the high efficiency, high density, dual 25A, single 50A switch mode step-down power module regulator. The input voltage is from 4.5V to 15V. The output voltage is programmable from 0.6V to 1.8V. DC2479A-A is configured as dual-phase, single-output, which can deliver up to 50A maximum. The board designs with minimum components to demonstrate this high efficiency, high density μModule. As explained in the data sheet, output current de-rating is necessary for certain VIN, VOUT, and thermal conditions. These features and the availability of the LTM4650EY in a compact 16mm × 16mm × 5.01mm BGA package make it ideal for use in many high-density point-of-load applications. The LTM4650 data sheet must be read in conjunction with this demo manual for working on or modifying the demo circuit DC2479A-A.
