Linear Technology's LTM4607IV - High-Efficiency, µModule Regulator

The LTM4607IV is a complete system-in-package (SiP) DC/DC step-down regulator from Linear Technology, now part of Analog Devices. This innovative µModule (micromodule) regulator integrates the DC/DC controller, power switches, inductor, and all support components into a compact, surface-mount package. Designed to be a high-efficiency, easy-to-use solution, the LTM4607IV requires only a few external components to operate and is ideal for space-constrained applications.

With an operating input voltage range of 4.5V to 28V, the LTM4607IV is versatile enough to handle a variety of input sources, including intermediate bus voltages and battery-powered applications. It can deliver a continuous output current up to 12A at output voltages ranging from 0.6V to 5V, making it suitable for powering FPGAs, ASICs, microprocessors, and general-purpose point-of-load (POL) applications.

The LTM4607IV boasts high efficiency, which is achieved through the use of a synchronous buck converter topology and state-of-the-art MOSFET technology. This efficiency minimizes heat generation, thereby reducing the need for extensive cooling systems and enabling the use of this µModule regulator in thermally sensitive environments.

Featuring robust protection features, the LTM4607IV includes overvoltage, overcurrent, and overtemperature protection, ensuring reliable operation under abnormal operating conditions. Additionally, the module offers tracking and margining capabilities, which are essential for sequencing and voltage adjustment in complex power systems.

The product comes in a rugged, thermally enhanced LGA package, which ensures excellent thermal performance and durability. The LTM4607IV's compact size (15mm x 15mm x 2.8mm) allows for a minimal footprint on the PCB, providing more space for other critical components.

Overall, the LTM4607IV from Linear Technology is an advanced, high-density power solution that simplifies the design of power supply systems, accelerates time-to-market, and delivers the performance and reliability that modern electronic systems require.
