Analog Devices Inc. Presents the LTM4639IY: A High-Performance µModule Regulator

The LTM4639IY is a feature-rich, high-efficiency, dual 20A or single 40A step-down DC/DC µModule (micromodule) regulator from Analog Devices Inc. This innovative product is an integral part of power management solutions, designed to meet the needs of space-constrained applications in telecommunications, networking, and industrial systems.

Compact and Powerful

With its compact over-molded package measuring just 16mm x 16mm x 5.01mm, the LTM4639IY is engineered to fit into the most space-restricted environments without sacrificing performance. It integrates the inductor, MOSFETs, a dual DC/DC regulator, and all supporting components within its LGA package, simplifying design and reducing external component count.

Efficient and Versatile

Efficiency is at the core of the LTM4639IY's design. It operates over an input voltage range of 4.5V to 15V and provides an adjustable output voltage from 0.6V to 1.8V, which is essential for today's low-voltage, high-current applications. Its high efficiency and dual-phase operation reduce input and output ripple and allow for the use of smaller capacitors.

Advanced Features for Enhanced Performance

The LTM4639IY boasts a rich set of features to enhance its performance, including:

• Precision Enable: Allows for a precise turn-on voltage threshold.
• Power Good Indicators: Provides reliable system monitoring by indicating when the output voltage is within nominal operating range.
• Tracking Capability: Enables the output voltage to track an external control voltage, simplifying sequencing in complex power systems.
• Overvoltage, Overcurrent, and Overtemperature Protection: Ensures the regulator operates safely under various fault conditions.

Easy to Use

Despite its sophisticated capabilities, the LTM4639IY is designed for ease of use. It requires only a few input and output capacitors and resistors to complete the power supply design, making it an ideal solution for quick and reliable power delivery.

Robust and Reliable

Analog Devices Inc. is known for its commitment to quality, and the LTM4639IY is no exception. It is designed to meet the rigorous standards required for industrial and high-reliability environments. The device is RoHS compliant and operates over a temperature range of -40°C to 125°C, ensuring performance across a wide range of operating conditions.

For engineers seeking a high-density, high-efficiency power solution, the LTM4639IY from Analog Devices Inc. represents a blend of innovation, performance, and reliability.
