Demonstration circuit 2453A features the LTM4643 μModule® regulator, a high performance high efficiency 4 output step-down regulator. The LTM4643EV has an operating input voltage range of 4V to 14V and is able to provide up to 3A out output current from each of its phases. Each output’s voltage is programmable from 0.6V to 5.5V but the demo board is configured to provide outputs of 3.3V, 2.5V, 1.5V and 1.2V. The LTM4643EV is a complete DC/DC point of load regulator in a thermally enhanced 15mm × 9mm × 5.01mm BGA package requiring only a few input and output capacitors.
