LTM4611EV - A High-Performance DC/DC µModule Regulator from Linear Technology

The LTM4611EV is a complete system-in-package (SiP) featuring a high-efficiency, high-density, dual 8A or single 16A output step-down DC/DC µModule (micromodule) regulator. Designed and manufactured by Linear Technology, now part of Analog Devices, this compact, encapsulated module integrates the inductor, MOSFETs, a DC/DC controller and supporting components within a 15mm x 15mm x 4.92mm LGA package. This level of integration simplifies design and accelerates time-to-market for applications demanding high performance and space efficiency.

The LTM4611EV operates over an input voltage range of 4.5V to 16V, making it versatile for a variety of applications including telecom and networking equipment, industrial devices, and high-density computing systems. The output voltage is adjustable from 0.8V to 1.8V, which is suitable for powering low voltage silicon such as FPGAs, ASICs, and microprocessors.

One of the key features of the LTM4611EV is its high efficiency, which reduces power loss and minimizes the need for extensive heat management. This is particularly beneficial in systems where space is at a premium and airflow is limited. The module also includes an internal temperature sensor and over-temperature protection, ensuring reliable operation under a wide range of conditions.

For applications requiring greater output current, up to four LTM4611EV modules can be paralleled with current sharing to deliver up to 64A of continuous output. This scalability allows designers to address future power needs without having to redesign the power supply.

The device also offers several features to improve performance and ease of use, including programmable soft-start, tracking, and margining. The power module is supported by extensive simulation tools and reference designs, helping engineers to quickly and accurately integrate the LTM4611EV into their designs.

Overall, the LTM4611EV from Linear Technology represents a powerful, flexible solution for modern high-density power supply requirements. Its small size, coupled with its robust feature set, makes it an excellent choice for designers looking to optimize their power systems for efficiency and space without compromising on performance.
