LT8614EUDC#PBF

Overview

The LT8614EUDC#PBF is a synchronous buck Silent Switcher regulator from Analog Devices, featuring a 42V input range and 4A continuous output current. It utilizes an integrated 2.5MHz switching frequency to balance efficiency and component size. The device incorporates Silent Switcher architecture for ultra-low EMI radiation without external snubbers. Key electrical parameters include a 30ns minimum top switch turn-on time, supporting high VIN-to-low VOUT conversions. It offers programmable frequency synchronization and burst mode operation for light-load efficiency.

Feature Summary

Silent Switcher architecture minimizes electromagnetic interference emissions
Integrated 4A synchronous power stage with 42V maximum input voltage
Burst Mode operation ensures high efficiency at light load currents
Programmable switching frequency allows synchronization to external clocks

Applications

Automotive infotainment and body control modules
Industrial distributed power systems
Point-of-load regulation for digital processors
Battery-powered equipment requiring low quiescent current

Procurement Notes

Verify the complete part number including the suffix against official Analog Devices documentation to ensure correct packaging and temperature grade. Confirm availability status through authorized distributors as supply conditions may vary. Cross-reference the datasheet revision date to ensure compatibility with current design requirements and regulatory standards.

Selection Notes

Select this component when designing systems requiring compact size and strict EMI compliance without additional filtering components. The 4A output capability suits moderate power applications. Consider the 2.5MHz fixed frequency for standard inductor selection. Evaluate thermal performance based on PCB copper area and ambient conditions for sustained 4A loads.

Part Context

This part belongs to the LT8614 family of Silent Switcher regulators. It shares architectural similarities with other members like the LT8640 but differs in output current rating and specific feature sets. The family targets applications demanding high efficiency and low noise in space-constrained environments.
