Analog Devices Inc. LTM4622AIY Product Overview

The LTM4622AIY is a high-performance, dual 2.5A or single 5A step-down µModule (micromodule) regulator from Analog Devices Inc., designed to meet the demands of space-constrained and power-dense applications. This compact, complete system in a package integrates the inductor, power switches, DC/DC controller, and compensation components in a tiny 6.25mm x 6.25mm x 5.01mm BGA (ball grid array) package. The LTM4622AIY is engineered to deliver precise voltage regulation and high efficiency while minimizing the amount of board space used.

With a wide input voltage range of 3.6V to 20V, the LTM4622AIY is suitable for a variety of applications, including industrial, automotive, and communication systems that require a compact, efficient power supply solution. The dual-channel configuration can be used to supply two separate outputs of up to 2.5A each or can be combined to provide a single output with a current capability of up to 5A, offering flexibility in design.

The LTM4622AIY boasts advanced features such as precision enable, power good indicators, and tracking, which allow for a controlled startup sequence and easy power management. Additionally, it supports frequency synchronization, spread spectrum operation, and has selectable Burst Mode operation for improved efficiency at light loads. This makes the LTM4622AIY an excellent choice for battery-powered systems and applications sensitive to noise, such as RF or precision measurement systems.

For thermal management, the LTM4622AIY utilizes a high-performance package with exposed top and bottom pads for improved heat dissipation. This design ensures reliable operation even at full load over a temperature range of -40°C to +125°C, making it suitable for harsh environments.

Overall, the LTM4622AIY from Analog Devices Inc. is a highly versatile, efficient, and space-saving solution for modern electronic systems requiring a high-quality power supply. Its ease of use, combined with the integration of multiple components into a single package, significantly reduces design complexity and accelerates time-to-market for engineers.
