LTM4616IV#PBF

The LTM4616IV#PBF is a dual 8 A per channel step-down DC/DC µModule regulator from Analog Devices, integrating a complete switching power supply—including the inductor, power MOSFETs, DC/DC controller, and compensation—into a compact land grid array (LGA) package. This high-density design accommodates a wide input voltage range as low as 2.375 V and provides two independent outputs adjustable from 0.6 V, with output tracking and margining capabilities that simplify sequencing and voltage margining in complex digital systems. The µModule architecture minimizes external component count, reduces layout sensitivity, and conserves board space, while the current-mode control loop ensures stable operation over a broad range of operating conditions. The LGA package offers a low-profile, surface-mount solution with robust thermal performance suitable for high-reliability environments.

Typical applications include point-of-load regulation for FPGAs, ASICs, microprocessors, and memory arrays in industrial automation, test and measurement equipment, telecommunications infrastructure, and avionics systems where tight board real estate and consistent performance are critical. The “IV” suffix designates an industrial temperature range of –40°C to +125°C, making the device appropriate for extended-environment operation without the cost premium of full military qualification. Analog Devices’ µModule products generally maintain extended lifecycles, lowering obsolescence risk for sustained defense and aerospace programs; procurement teams should verify current lifecycle status through authorized channels. The part is supplied in a RoHS-compliant, lead-free finish (#PBF), and consolidating over a dozen discrete components into a single module reduces bill-of-material count and simplifies supply-chain management for high-reliability electronics manufacturing.
