LT8608EMSE#TRPBF

Overview

The LT8608EMSE#TRPBF is a synchronous step-down switching regulator from Analog Devices, housed in a 10-lead MSOP package with an exposed pad. It operates within an input voltage range of 3V to 42V and delivers a continuous output current of 1.5A. The device features an adjustable switching frequency between 200kHz and 2.2MHz and maintains a quiescent current of 1.7µA during operation. It supports Burst Mode operation for low noise and high efficiency at light loads.

Feature Summary

• Compact high-efficiency synchronous monolithic step-down topology
• Ultra-low quiescent current consumption for extended battery life
• Internal compensation enabling the use of small external inductors
• Precise enable pin threshold supporting undervoltage lockout or shutdown

Applications

• General-purpose DC-DC conversion
• Low EMI power supply designs
• Battery-powered portable electronics
• Industrial control systems

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the EMSE designation corresponds to the MSOP-10 package variant. Ensure compatibility with the required thermal dissipation requirements for the selected operating conditions. Cross-reference the manufacturer's latest datasheet for any updates to electrical characteristics or recommended operating conditions prior to finalizing procurement specifications.

Selection Notes

Select this component for applications requiring a wide input voltage range up to 42V with moderate output current needs. The internal compensation simplifies design by reducing the number of external components. Consider the MSOP-10 package constraints regarding thermal performance and board space. Evaluate the need for spread spectrum frequency modulation if strict EMI limits are required for the target application environment.

Part Context

This part belongs to the LT8608 family of micropower buck regulators designed for space-constrained environments. It shares architectural similarities with other members like the LT8609 and LT8610 but offers lower output current capabilities. The series emphasizes low static current and fast transient response, making it suitable for systems where power conservation and compact form factors are critical design drivers.

Replacement Considerations

LT8608IMSE#TRPBF serves as a direct functional substitute within the same package and specification profile.
