LT8608HMSE#TRPBF

Overview

The LT8608HMSE#TRPBF 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 1.5A. The device features adjustable output voltage, a switchable frequency between 200kHz and 2.2MHz, and ultra-low quiescent current of 2.5µA in Burst Mode operation. It utilizes peak current mode topology for fast transient response and includes internal compensation. The component is housed in a 10-MSOP package with an exposed pad and supports junction temperatures from -40°C to +150°C.

Feature Summary

Synchronous buck topology with integrated high-side and low-side MOSFETs
Ultra-low quiescent current consumption in Burst Mode operation
Internal compensation allowing use of small external inductors
Programmable soft-start and accurate undervoltage lockout threshold

Applications

Battery-powered portable equipment requiring extended runtime
Industrial control systems with wide input voltage ranges
Automotive electronics operating within specified temperature limits
Point-of-load regulation for digital signal processors

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging with lead-free finish. Confirm the HMSE grade meets required thermal and electrical specifications for the target application environment. Cross-reference the manufacturer datasheet for exact pinout and recommended external component values to ensure proper implementation.

Selection Notes

Select this component when a compact solution is needed for high-efficiency power conversion from 42V sources. The wide input range accommodates various battery chemistries and automotive loads. Consider the MSOP package size constraints and thermal dissipation requirements associated with the 1.5A output capability in the final design.

Part Context

This part belongs to the LT8608 family of high-speed synchronous step-down regulators. It shares architectural similarities with other members like the LT8607 and LT8606 but offers higher current capacity. The family is designed for applications demanding high efficiency across light and heavy load conditions while maintaining minimal footprint.
