LT8608SEV#TRPBF

Overview

The LT8608SEV#TRPBF is a synchronous step-down switching regulator from Analog Devices, operating with an input voltage range of 3.0 V to 42 V and delivering up to 1.5 A of continuous output current. It features a low quiescent current of 1.7 µA in Burst Mode operation, maintaining high efficiency at light loads while keeping output ripple below 10 mV. The device supports adjustable switching frequencies between 200 kHz and 2.2 MHz, utilizing internal compensation for fast transient response and stability with small inductors. It is housed in a compact 10-lead MSOP package.

Feature Summary

• Features ultra-low quiescent current consumption in Burst Mode operation for extended battery life.
• Includes internal compensation to minimize external component count and ensure loop stability.
• Provides programmable soft-start and tracking capabilities via the TR/SS pin.

Applications

• General-purpose step-down voltage regulation
• Low EMI power supply designs
• Battery-powered portable electronics

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required thermal management solutions for the selected enclosure. Cross-reference datasheet revisions to validate electrical characteristics and pinout assignments before finalizing procurement specifications.

Selection Notes

Select this component when a wide input voltage range up to 42 V is required alongside moderate output current capabilities. Consider the MSOP package constraints for thermal dissipation and board space. Evaluate the need for spread spectrum frequency modulation if electromagnetic interference reduction is critical for the target application environment.
