LX9610 Power Module 12A, 22V, Step-Down Power Module Description The Microsemi® LX9610 is a 22V, 12A power module designed for step-down point-of-load applications. This device includes a synchronous controller with compensation built-in, internal power MOSFETs, and the output inductor all in a 15mm x 15mm QFN package. It will operate with an input voltage from 8V to 22V, while the output voltage is adjustable from 0.8V to 5V, using a single external resistor. Included is an internal 5V regulator, and the only other components needed to make a complete 12A DC to DC converter are a 4.7μF decoupling capacitor for the 5V regulator, and the bulk input and output capacitors. The LX9610 is packaged in a thermal enhanced, compact over-molded module with a length, width and height of the power module are 15mm, 15mm and 4mm. This package is suitable for assembly by standard automated surface mount equipment.
