DC1889A

Demonstration Board, Step Down DC-DC Regulator, High Efficiency, Input Voltage of 4V-14V

The demonstration board features LTM4624EY DC to DC µModule regulator. The LTM4624EY is a complete 4A step down switching mode µModule micromodule regulator. Included in the IC package are the switching controller, power FETs, inductor and support components. The LTM4624EY has an operating input voltage range of 4V to 14V and is able to provide an output current of up to 4A. The output voltage is programmable from 0.6V to 5.5V. The LTM4624EY is a complete DC to DC point of load regulator in a thermally enhanced 6.25mm x 6.25mm x 5.01mm BGA package requiring only a couple capacitors and a resistor. Output voltage tracking is available through the TRACK/SS pin for supply rail sequencing.
