LT8551EUKG#TRPBF

Overview

The LT8551EUKG#TRPBF is a high-voltage boost switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 3.6V to 80V and supports output voltages up to 80V. The device features synchronous rectification for improved efficiency and offers adjustable output control via a single feedback pin. It utilizes a 52-WFQFN package with exposed pad for thermal performance. The integrated switch handles high current capabilities suitable for demanding power applications.

Feature Summary

Supports wide input voltage range up to 80V
Integrated synchronous rectification for high efficiency
Adjustable output voltage via single feedback pin
High operating junction temperature capability

Applications

Industrial automation power supplies
Battery charging systems
LED lighting drivers
Telecommunications equipment

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the E grade designation matches required temperature specifications. Ensure compatibility with 52-pin QFN footprint during PCB layout. Check RoHS compliance status if restricted substances are prohibited in your assembly process.

Selection Notes

Choose this component when high input voltage tolerance is required alongside efficient step-up conversion. The synchronous design reduces external component count compared to non-synchronous alternatives. Consider thermal dissipation requirements due to the high power density in the 52-QFN package. Validate that the 80V output limit meets system voltage constraints.

Part Context

This part belongs to the LT8551 family of high-voltage boost converters designed for robust industrial applications. It complements other Analog Devices PMIC solutions by offering extended voltage ranges. The series focuses on simplifying design through integrated power switches and control logic.
