DC2249B, Demonstration Board, LTM4622EV#PBF, Ultrathin Dual 2.5 A Step-Down µModule Regulator

DC2249B is a LTM4622 ultra-thin dual 2.5A step-down µModule regulator demonstration board. Demonstration circuit 2249B features the LTM®4622 µModule® regulator, a tiny low profile high performance high efficiency dual step-down regulator. The LTM4622 has an operating input voltage range of 3.6V to 20V and is able to provide an output current of up to 2.5A for each channel. Each output's voltage is programmable from 0.6V to 5.5V. The LTM4622 is a complete DC-DC point of load regulator in a low profile thermally enhanced 6.25mm x 6.25mm x 1.82mm LGA package requiring only a few input and output capacitors. Output voltage tracking is available through the TRACK/SS pin for supply rail sequencing. External clock synchronization is available through the SYNC/MODE pin. For high efficiency at low load currents the MODE pin jumper selects the Burst Mode® option for operation in less noise sensitive applications.
