Analog Devices Inc. LTM4642EY#PBF Dual 4A or Single 10A DC/DC µModule Regulator

The LTM4642EY#PBF is a high-performance dual 4A or single 10A output DC/DC µModule (micromodule) regulator from Analog Devices Inc. that integrates the inductor, power switches, DC/DC controller, and compensation in a compact, encapsulated package. Designed for space-constrained applications, this product is ideal for telecommunications, industrial, and medical equipment, as well as for aerospace and test instrumentation systems.

With its advanced design, the LTM4642EY#PBF offers a wide input voltage range from 2.375V to 5.5V, making it suitable for single Li-Ion, multi-cell alkaline, or NiMH, as well as 3.3V and 5V intermediate bus systems. The output voltage is adjustable from 0.6V to 3.3V, which allows for versatility in different applications. The device can be configured as two separate 4A outputs or combined to provide a single 10A output, providing flexibility for the power design of complex systems.

Featuring fast transient response and high efficiency, the LTM4642EY#PBF ensures reliable performance even in demanding situations. Its high switching frequency and current mode control enable a very fast response to line and load changes without sacrificing stability. Additionally, the device supports frequency synchronization and has selectable Burst Mode® operation for improved efficiency at light loads.

The LTM4642EY#PBF is designed with protection features that include overvoltage, overcurrent, and over-temperature protection, ensuring the safety and longevity of both the regulator and the system it powers. The compact (15mm x 15mm x 5.01mm) BGA package is RoHS compliant and is designed for automated assembly by standard surface mount equipment.

Overall, the LTM4642EY#PBF from Analog Devices Inc. offers a highly integrated, efficient, and flexible solution for power management, reducing the need for multiple components and simplifying the design process for engineers.
