Overview
The LTM4622EY#PBF, produced by Analog Devices Inc., is a dual 2.5A step-down switching mode power µModule (power module) regulator. This compact device is available in ultrathin 6.25mm × 6.25mm × 1.82mm LGA and 6.25mm × 6.25mm × 2.42mm BGA packages. It integrates the switching controller, power FETs, inductor, and other necessary support components, making it a complete power solution. The LTM4622 operates over an input voltage range of 3.6V to 20V and supports output voltages from 0.6V to 5.5V, which can be set using a single external resistor. This regulator is designed for high efficiency and can deliver dual 2.5A continuous output current, with a peak current of 3A.
