LTM4609MPY#PBF - High Efficiency, DC/DC µModule Regulator

The LTM4609MPY#PBF is a complete system-in-a-package (µModule) step-down regulator from Linear Technology, now part of Analog Devices, Inc. This high-performance power management IC integrates the inductor, power switches, DC/DC controller, compensation components, and the necessary support components all within a compact, surface-mount package.

Designed for a variety of applications, including telecommunications, industrial systems, and automotive products, the LTM4609MPY#PBF is capable of delivering a high power density and simplifying the design process for engineers. It operates over an input voltage range of 4.5V to 36V and can provide an adjustable output voltage from 0.8V to 34V, which makes it versatile for both step-down and step-up applications.

The device features a high efficiency design that reduces heat dissipation and improves system reliability. It can deliver up to 10A of continuous output current with excellent load and line regulation. The LTM4609MPY#PBF also supports frequency synchronization, output voltage tracking, and has a power good indicator for system monitoring and diagnostics.

Safety and protection features are built into the LTM4609MPY#PBF, including overvoltage, overcurrent, and over-temperature protection, ensuring the longevity and reliability of both the µModule and the system it is used within. The package is designed to operate in harsh environments and can withstand military-grade temperature ranges, making it suitable for high-reliability applications.

The LTM4609MPY#PBF simplifies board layout and reduces external component count, which is critical in space-constrained applications. Its compact size (15mm x 15mm x 2.82mm) and surface-mount LGA package make it easy to integrate into a wide range of designs. With its robust design and integrated approach, the LTM4609MPY#PBF offers a highly efficient, reliable, and easy-to-use solution for complex power supply requirements.
