LT1767EMS8E#PBF

Overview

The LT1767EMS8E#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 1.25MHz and supports an input voltage range from 3V to 25V. The device provides an adjustable output voltage and delivers up to 1.2A of output current. It features a high-efficiency internal switch, current mode control for fast transient response, and a shutdown function. The component is housed in an 8-MSOP-EP package and operates within a temperature range of -40°C to +125°C.

Feature Summary

Integrates a high-efficiency 1.5A switch with complete current mode control circuitry on a single die
Provides fast transient response and excellent loop stability through fixed 1.25MHz operation
Includes a shutdown pin for power management and low quiescent current consumption

Applications

Portable equipment requiring efficient step-down conversion
Battery-powered systems needing low standby current
General-purpose DC-DC regulation in industrial environments

Procurement Notes

Verify the exact part number suffix against manufacturer documentation to confirm package type and lead-free status. Ensure compatibility with required thermal dissipation methods for the MSOP-EP package. Confirm availability status as supply constraints may affect procurement timelines. Cross-reference datasheet revisions to ensure design compliance with latest electrical specifications.

Selection Notes

Select this component when a compact solution with adjustable output voltage is required. Consider the 1.25MHz frequency for balancing efficiency and external component size. Evaluate thermal performance requirements given the small surface mount package. Verify that the input voltage range covers the specific application's supply variations.

Part Context

This part belongs to the LT1767 family of monolithic buck regulators. It shares core architecture with variants offering fixed output voltages such as 1.8V, 2.5V, 3.3V, and 5.0V. The EMS8E designation indicates an 8-pin MSOP package with an exposed pad for improved thermal performance compared to standard MSOP packages.
