LTM4616MPY#PBF

The LTM4616MPY#PBF from Analog Devices is a complete dual 8A step-down DC/DC μModule regulator integrating the controller, power MOSFETs, inductor, and compensation in a low-profile LGA package. Operating from a low input voltage range, the device generates two independent outputs each capable of 8A continuous current, with output voltages adjustable down to 0.8V and tight line and load regulation. Key technical characteristics include current-mode control for stable operation across a wide range of output capacitors, optional external clock synchronization to system frequencies, and output voltage tracking for controlled sequencing of multiple rails. The integrated inductor and power components minimize layout complexity and EMI, while the LGA substrate provides efficient thermal dissipation to the PCB.

This module is widely used in high-reliability point-of-load power supplies for defense and aerospace electronics, such as radar processors, avionics computers, and ruggedized communication gear, as well as in industrial embedded systems deployed in extreme environments. The MP suffix designates a military-grade plastic device rated for junction temperatures from –55°C to +125°C, delivering a cost-effective yet robust alternative to ceramic-packaged military components. From a procurement perspective, the LTM4616 family is fully supported by Analog Devices with a commitment to long lifecycle availability, reducing obsolescence risk for long-duration defense and aerospace programs. The #PBF suffix indicates lead-free terminations and RoHS compliance, while the LGA package is compatible with standard surface-mount assembly processes.
