DC2171A-A

DC2171A-A demonstration circuit features the LTM®4623 µModule® regulator, a tiny low profile high-performance step-down regulator. The LTM4623 has an operating input voltage range of 4V to 20V and can provide an output current of up to 3A. The output voltage is programmable from 0.6V to 5V. The LTM4623 is a complete DC/DC point of load regulator in a 6.25mm × 6.25mm × 1.82mm round pad LGA 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.

• 1MHz default operating frequency
• 83.2% efficiency at VIN = 12V, VOUT = 1.8V, IOUT = 3A
