LT8619EMSE-5#TRPBF

Overview

The LT8619EMSE-5#TRPBF is a synchronous monolithic step-down switching regulator from Analog Devices. It features a wide input voltage range of 3V to 60V and delivers up to 1.2A output current. The device operates with an ultralow quiescent current of 6μA and includes Burst Mode operation for enhanced light-load efficiency. It utilizes a fast minimum switch-on time of 30ns and offers adjustable or fixed output voltages, packaged in a 16-TFSOP (MSOP) exposed pad.

Feature Summary

• Synchronous monolithic buck topology
• Wide 3V to 60V input range
• Ultralow 6μA quiescent current
• Burst Mode operation for high efficiency

Applications

• Industrial point-of-load regulation
• Automotive electronics systems
• Battery-powered equipment
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging. Confirm the -5 variant provides a fixed 5V output. Ensure compatibility with the 16-TFSOP exposed pad thermal requirements. Check RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a compact solution is required for inputs up to 60V. The fixed 5V output simplifies design for standard logic rails. Consider the 1.2A limit for load requirements. The exposed pad package necessitates adequate PCB thermal management for sustained high-current operations.

Part Context

This part belongs to the LT8619 family of high-efficiency synchronous buck regulators. It shares architectural similarities with other ADI power management ICs but is distinguished by its specific 60V rating and 1.2A current capability. The MSOP-EP package allows for space-constrained designs in dense electronic assemblies.

Replacement Considerations

LT8619EMSE-5#PBF: Identical electrical specifications but in tube packaging instead of tape-and-reel.
