LT8607EMSE#PBF

Overview

The LT8607EMSE#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 a continuous output current of 750mA. The device features an adjustable output voltage and supports programmable switching frequencies between 200kHz and 2.2MHz. Quiescent current consumption is specified at 2.5µA, supporting high efficiency in low-power applications. The component is housed in a 10-lead MSOP package with an exposed pad for thermal management. It functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Synchronous buck topology providing high conversion efficiency
• Ultra-low quiescent current operation for battery-powered systems
• Programmable switching frequency allows optimization for size or performance
• Wide input voltage range suitable for various power sources

Applications

• Industrial control systems requiring isolated or non-isolated DC-DC conversion
• Battery-operated portable equipment needing extended runtime
• Embedded computing platforms with variable input supply rails
• Telecommunications infrastructure power distribution networks

Procurement Notes

Verify the specific suffix #PBF indicates lead-free RoHS compliance before ordering. Confirm the MSOP-10 package availability matches your PCB footprint requirements. Check current distributor stock levels as supply constraints may affect delivery schedules. Ensure the operating temperature range meets your system's environmental specifications. Validate that the 750mA output current rating satisfies your maximum load demands under all conditions.

Selection Notes

Select this component when a wide input voltage range up to 42V is required alongside compact packaging. The adjustable output voltage offers flexibility for different logic levels. Consider the 2.5µA quiescent current for standby power sensitivity. Evaluate the thermal performance of the MSOP-10 package against your board's heat dissipation capabilities. Compare switching frequency options to balance electromagnetic interference and external component size.

Part Context

This part belongs to the LT8607 family of synchronous step-down regulators from Analog Devices. The series is designed for applications demanding high efficiency and low standby power. Other variants in the family may offer different output currents or package types. The EMSE#PBF designation specifies the industrial temperature grade and lead-free packaging. This family targets modern power management needs in space-constrained designs.

Replacement Considerations

LT8607HMSE#PBF serves as a verified substitute within the same product family. Both parts share identical electrical characteristics and pin configurations. Verify that the replacement part number matches the required package style. Confirm that any suffix differences do not alter the functional specifications. Ensure compatibility with existing PCB layouts when swapping these components.
