LT8643SEV#PBF

Overview

The LT8643SEV#PBF is a Silent Switcher 2 synchronous step-down DC/DC converter from Analog Devices. It features an input voltage range of 3.4 V to 42 V and delivers up to 6 A output current. The device offers adjustable output voltage with a minimum of 0.97 V. Key electrical parameters include a quiesient current of 750 nA and operating supply current of 350 uA. The switching frequency is programmable from 200 kHz to 3 MHz. It operates within a temperature range of -40°C to +125°C and is housed in a 24-lead LQFN package.

Feature Summary

Integrates Silent Switcher 2 architecture for minimized radiated EMI without external filters.
Provides high efficiency across wide load ranges through synchronous buck topology.
Supports flexible design via adjustable switching frequency and external compensation options.

Applications

Industrial automation control systems
Infrastructure network equipment power distribution
Point-of-load regulation for embedded processors

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure the ordered part matches the required package type and lead-free status. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high input voltages up to 42 V with significant current demands. Consider the LQFN package for space-constrained layouts. Evaluate the need for external compensation if utilizing the -2 variant, though the standard SEV model integrates internal compensation for simplified implementation.

Part Context

This part belongs to the LT8643S Silent Switcher 2 family, designed for high-performance power management. It complements other Analog Devices PMICs by offering robust protection features and compact integration. The series targets applications demanding low electromagnetic interference and high reliability in harsh environments.
