LT8625SPJV#TRMPBF

Overview

The LT8625SPJV#TRMPBF is a synchronous step-down switching regulator from Analog Devices, part of the Silent Switcher 3 family. It features an integrated input filter for ultralow EMI and operates with an input voltage range of 2.7V to 18V. The device delivers up to 8A of output current in a compact 24-TFQFN package. It supports adjustable switching frequencies from 300kHz to 4MHz and includes programmable soft-start. The regulator provides positive, adjustable output voltage with high efficiency across various load conditions.

Feature Summary

• Silent Switcher 3 architecture integrates input capacitors and switches to minimize radiated electromagnetic interference without external shielding.
• Synchronous buck topology ensures high conversion efficiency by utilizing internal low-resistance MOSFETs for both high-side and low-side switching.
• Wide input voltage capability allows direct connection to standard 5V, 9V, and 12V power rails while supporting higher bus voltages up to 18V.

Applications

• Point-of-load regulation for industrial control systems and instrumentation
• Power supply stages for embedded processors and field-programmable gate arrays
• Battery-powered equipment requiring efficient voltage translation from single-cell or multi-cell sources

Procurement Notes

Verify the specific suffix JV against the official datasheet to confirm pinout compatibility and thermal pad configuration. Ensure the ordering part number matches the exact tape and reel specifications required for surface-mount assembly processes. Cross-reference the manufacturer's latest documentation for any product change notifications affecting this variant.

Selection Notes

Select this component when system design demands strict electromagnetic interference limits alongside high current density. The integrated filter reduces the need for bulky external shielding components. Evaluate the thermal performance within the 24-TFQFN package to ensure adequate heat dissipation for continuous 8A operation under expected ambient conditions.

Part Context

This part belongs to the LT8625 series, which represents Analog Devices' third-generation silent switcher technology. The series focuses on reducing noise emissions in compact power designs. The SPJV designation indicates a specific version optimized for high-current applications within the 18V input range, distinguishing it from lower-current variants in the same family.
