Description
Demonstration circuit 2568A features the LTM®4622AµModule® regulator, a tiny low profile high performancehigh efficiency dual step-down regulator. The LTM4622Ahas an operating input voltage range of 3.6V to 20V andis able to provide an output current of up to 2A for eachchannel. Each output’s voltage is programmable from 1.5Vto 12V. The LTM4622A is a complete DC/DC point of loadregulator in a low profile thermally enhanced 6.25mm ×6.25mm × 1.82mm LGA package requiring only a few inputand output capacitors. Output voltage tracking is availablethrough the TRACK/SS pin for supply rail sequencing. Externalclock synchronization is available through the MODEpin. For high efficiency at low load currents, the MODE pinjumper (JP3) selects the Burst Mode® option for operationin less noise sensitive applications. The LTM4622A datasheet must be read in conjunction with this demo manualfor working on or modifying demo circuit 2568A.
