LT8610ACEMSE#PBF

Overview

The LT8610ACEMSE#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 42V and delivers up to 3.5A of output current. The device features a fixed output voltage of 41.8V, making it suitable for high-voltage applications. It supports a switching frequency range from 200kHz to 2.2MHz. The component functions within a junction temperature range of -40°C to +125°C and exhibits a quiescent current of 17µA. It is housed in a 16-MSOP package with an exposed pad.

Feature Summary

Integrated synchronous rectification for improved efficiency
Fixed output voltage configuration at 41.8V
Wide input voltage capability supporting up to 42V
Adjustable switching frequency ranging from 200kHz to 2.2MHz

Applications

Industrial power supply systems
Telecommunications infrastructure equipment
Embedded computing platforms requiring stable high-voltage rails
Automotive electronics subsystems

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when sourcing samples or evaluation units. Confirm that the AC variant matches the required 41.8V fixed output specification rather than adjustable versions. Ensure compatibility with 16-MSOP footprint requirements during PCB layout. Check manufacturer documentation for any recent PCN updates regarding epoxy changes or marking modifications.

Selection Notes

Select this part when a fixed 41.8V output is required without external feedback resistors. The 3.5A current rating suits moderate load applications. Consider the 17µA quiescent current for standby power constraints. Evaluate thermal performance given the MSOP package size against expected heat dissipation needs. Compare against adjustable variants if voltage flexibility is needed later.

Part Context

This component belongs to the LT8610 family of micropower buck regulators designed for space-constrained applications. The AC designation specifies the fixed 41.8V output version. It shares architectural similarities with other members like the LT8610AIMSE but differs in output configuration and quiescent current specifications. The EMSE suffix denotes the 16-lead MSOP package with an exposed thermal pad.
