LT8620MPMSE#TRPBF

Overview

The LT8620MPMSE#TRPBF is a synchronous monolithic step-down switching regulator manufactured by Analog Devices Inc. It features a wide input voltage range from 3.4 V to 65 V and delivers an adjustable output voltage between 970 mV and 64.75 V with a maximum output current of 2 A. The device operates at switch frequencies ranging from 200 kHz to 2.2 MHz and maintains a low quiescent current of 2.5 uA. It is housed in a 16-MSOP package with an exposed pad and supports operating temperatures from -55°C to +150°C.

Feature Summary

• Synchronous buck topology for high efficiency
• Wide 65V input voltage capability
• Low quiescent current operation
• Adjustable output voltage control

Applications

• Industrial power supplies
• Distributed power systems
• Point-of-load regulation
• Battery-powered equipment

Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging, distinct from the tube-packaged #PBF variant. Confirm the MP designation meets military temperature specifications (-55°C to +150°C). Ensure compatibility with the 16-MSOP footprint during procurement validation.

Selection Notes

Select this component for applications requiring high input voltages up to 65V in a compact surface-mount package. The adjustable frequency allows optimization for size versus efficiency trade-offs. Verify thermal requirements due to the exposed pad design for heat dissipation.

Part Context

This part belongs to the LT8620 family of micropower synchronous step-down regulators. It shares architectural similarities with other members like the LT8620IMSE but differs in package type and temperature rating. The MP grade ensures reliability in harsh environments compared to standard industrial grades.

Replacement Considerations

LT8620MPMSE#PBF offers identical electrical performance but uses tube packaging instead of tape and reel.
