LT8610EMSE#PBF

Overview

The LT8610EMSE#PBF is a synchronous step-down switching regulator from the Analog Devices LT8610A series. It operates with an input voltage range of 3.4 V to 42 V and delivers up to 2.5 A output current. The device features adjustable output voltage starting from 0.97 V, with a fixed-frequency operation between 200 kHz and 2.2 MHz. It maintains a low quiescent current of 2.5 µA and functions within a temperature range of -40°C to +125°C. Packaged in a 16-lead MSOP with exposed pad.

Feature Summary

• Synchronous buck topology for high efficiency
• Wide 42V input voltage capability
• Low quiescent current for battery applications
• Adjustable output voltage via external resistors

Applications

• Industrial point-of-load regulation
• Battery-powered equipment power management
• Embedded system voltage conversion
• Telecommunications infrastructure power supplies

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and thermal characteristics. Ensure compatibility with required output voltage settings using external feedback resistors. Confirm RoHS compliance status through manufacturer datasheets prior to integration into final assemblies.

Selection Notes

Select this component when a wide input voltage range up to 42V is required in a compact surface-mount package. It is suitable for designs needing adjustable output voltages with moderate current demands. Consider thermal performance requirements due to the MSOP-16EP package constraints under heavy load conditions.

Part Context

This part belongs to the LT8610A family of micropower synchronous buck regulators. It shares core architecture with variants like LT8610ABEMSE#PBF but differs in output configuration. The EMSE suffix denotes the specific MSOP-16EP package variant designed for efficient heat dissipation in space-constrained PCB layouts.

Replacement Considerations

LT8610ABEMSE#PBF offers similar electrical characteristics with fixed output options.
