DC2171A-B - LTM4625 Demo Board | Step-Down μModule Regulator, 4V ≤ VIN ≤ 20V, Vout = 0.6V to 5V @ 5A
Demonstration circuit 2171A-B features the LTM®4625 μModule® regulator, a tiny low profile high performance step-down regulator. The LTM4625 has an operating input voltage range of 4V to 20V and is able to provide an output current of up to 5A. The output voltage is jumper-selectable and can be set to 1.0V, 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V or a user-defined value from 0.6V to 5V. The LTM4625 is a complete DC/DC point-of-load regulator in a 6.25mm × 6.25mm × 5.01mm BGA package requiring only a few input and output capacitors.
