Overview
The LT8625SPJV#TRPBF is a synchronous step-down DC-DC converter from the Silent Switcher 3 family, manufactured by Analog Devices Inc. It features an adjustable output voltage with a maximum current of 8A and operates within an input voltage range of 2.7V to 18V. The device supports switching frequencies between 300kHz and 4MHz and utilizes a 24-TFQFN package with an exposed pad for thermal management.
Feature Summary
- Integrates Silent Switcher 3 technology for minimized electromagnetic interference (EMI) radiation without requiring external ferrite beads.
- Provides high-efficiency synchronous rectification for stable power delivery in compact designs.
- Features an ultralow noise reference to ensure clean power supply for sensitive analog and RF circuits.
Applications
- Industrial automation systems requiring robust power regulation
- Distributed power architectures in enterprise infrastructure
- Point-of-load conversion for communication equipment
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm RoHS3 compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact pinout and thermal requirements of the target PCB layout design.
Selection Notes
Select this component for applications demanding high current density and strict EMI limits. Evaluate the required switching frequency against inductor size constraints. Consider the 24-TFQFN package thermal performance relative to the expected ambient temperature and load conditions during system design.
Part Context
This regulator belongs to the LT8625S series, designed for high-performance power management. It represents an evolution in silent switching technology, offering improved noise performance compared to previous generations while maintaining high efficiency across wide input voltage ranges.
Replacement Considerations
LT8625SPJV-1#TRPBF offers similar functionality with potential variations in internal reference characteristics or pin compatibility that require datasheet verification before substitution.
