LT8619IMSE#PBF

Overview

The LT8619IMSE#PBF is a synchronous monolithic buck regulator manufactured by Analog Devices Inc. It features an input voltage range of 3V to 60V and delivers up to 1.2A output current. The device operates with a switching frequency between 300kHz and 2.2MHz, utilizing a 16-lead MSOP package with exposed pad for thermal dissipation. Quiescent current is specified at 6µA, supporting efficient power management in space-constrained designs.

Feature Summary

Synchronous rectification architecture for enhanced efficiency
Wide input voltage capability accommodating various supply rails
Low quiescent current operation for standby power conservation
Integrated thermal performance via exposed pad packaging

Applications

Industrial automation systems
Automotive electronics
Portable instrumentation
Medical ultrasound equipment
Wireless infrastructure transceivers

Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free compliance and RoHS adherence when sourcing. Confirm the package type matches the 16-MSOP specification with an exposed thermal pad for proper heat dissipation. Ensure the ordering part number aligns with the exact manufacturer designation to avoid compatibility issues with existing board layouts or thermal management strategies.

Selection Notes

Select this component for applications requiring high input voltages up to 60V within a compact footprint. The fixed 5V output configuration simplifies design for standard logic supplies. Consider the 1.2A current limit for moderate load requirements. Evaluate the 300kHz to 2.2MHz frequency range against EMI constraints and inductor size requirements for the target application environment.

Part Context

This part belongs to the LT8619 series of synchronous buck regulators from Analog Devices. It is designed for high-speed conversion with low noise characteristics. The IMSE variant specifically denotes the MSOP-16 package with an exposed pad, optimized for surface-mount assembly and thermal performance in dense PCB layouts compared to through-hole alternatives.
