LT1767EMS8-2.5#TRPBF

Overview

The LT1767EMS8-2.5#TRPBF is a monolithic buck switching regulator from Analog Devices Inc., operating at a fixed frequency of 1.25MHz. It integrates a high-efficiency 1.5A power switch and complete current-mode control circuitry within an 8-pin MSOP package with exposed pad. The device supports an input voltage range of 3V to 25V and provides a fixed output voltage of 2.5V. It features synchronous rectification, adjustable soft-start, and operates over a junction temperature range of 0°C to 125°C.

Feature Summary

Integrates a high-efficiency 1.5A power switch with all necessary control circuitry for high-frequency operation
Utilizes current-mode control architecture to ensure fast transient response and excellent loop stability
Includes adjustable soft-start functionality to limit inrush current during startup

Applications

Buck converter circuits requiring fixed 2.5V output
Dual source supply configurations utilizing the integrated switch
SEPIC converter reference designs for specific input-output relationships

Procurement Notes

Verify the exact part number suffix #TRPBF to confirm tape and reel packaging and RoHS compliance status. Ensure the ordering information matches the specific 2.5V fixed output variant. Cross-reference the manufacturer's latest datasheet for any recent material declarations or epoxy changes that may affect assembly processes.

Selection Notes

Select this component when a compact solution for step-down conversion is required with integrated power switching capabilities. The fixed 2.5V output eliminates external resistor networks for basic regulation. Consider the 1.25MHz switching frequency for balancing component size against efficiency requirements in space-constrained applications.

Part Context

This part belongs to the LT1767 family of monolithic DC-to-DC converters. The EMS8 designation indicates the 8-lead MSOP package with an exposed thermal pad for improved heat dissipation. The -2.5 suffix specifies the internal fixed output voltage setting, distinguishing it from other variants like the 1.8V or 3.3V versions within the same series.
