DC2171A-B

DC2171A-B demonstration circuit 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 programmable 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. Output voltage tracking is available through the TRACK/ SS pin for supply rail sequencing. CLKIN, CLKOUT and PHMODE pins are available for clock synchronization and interleaving.
