Mingjiada Supply ADI LTM4622IY Dual 2.5A Step-Down Switching Mode μModule Regulator

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the [ADI] LTM4622IY dual-channel 2.5A step-down switching mode µModule® (micro-module) regulator. The LTM4622IY is available in compact, ultra-thin 6.25mm x 6.25mm x 1.82mm LGA and 6.25mm x 6.25mm x 2.42mm BGA packages. The package integrates a switch controller, power FETs, inductors and supporting components.

LTM4622IY operates over an input voltage range of 3.6V to 20V and supports an output voltage range of 0.6V to 5.5V (set by a single external resistor). The device’s high-efficiency design delivers a dual-channel output current of 2.5A continuous and 3A peak. Only a small number of ceramic input and output capacitors are required.
