Overview
The LT1767EMS8E-2.5#TRPBF is a monolithic buck switching regulator manufactured by 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 an exposed pad. The device supports an input voltage range from 3V to 25V and provides a fixed output voltage of 2.5V. It is designed for applications requiring fast transient response and excellent loop stability, suitable for surface-mount assembly in environments ranging from 0°C to 125°C junction temperature.
Feature Summary
- Integrates a high-efficiency 1.5A power switch and all necessary control circuitry for high-frequency operation
- Utilizes current-mode control architecture to ensure rapid transient response and robust loop stability
- Supports both Buck and SEPIC topologies for versatile DC-to-DC conversion requirements
Applications
- Buck converter circuits with adjustable soft-start capabilities
- Dual-output SEPIC converter designs
- Dual source supply configurations requiring low reverse leakage
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the exposed pad (EP) variant matches the thermal management requirements of the target PCB layout. Ensure compatibility with RoHS3 standards if environmental compliance is mandatory for the production line. Cross-reference the exact part number with official distributor catalogs to avoid confusion with non-exposed pad or different output voltage variants.
Selection Notes
Select this component when a fixed 2.5V output is required from an input range up to 25V. The 1.5A current capacity suits moderate load applications. Consider the 8-MSOP-EP package for thermal dissipation needs. Verify that the 1.25MHz switching frequency aligns with external component size constraints and EMI requirements compared to lower-frequency alternatives.
Part Context
This part belongs to the LT1767 family of monolithic switching regulators. Variants such as LT1767EMS8-1.8 and LT1767EMS8E-3.3 offer different fixed output voltages while sharing the same core topology and package style. The series is characterized by its integrated power switch and current-mode control, distinguishing it from discrete solutions or linear regulators like the LT1762.
Replacement Considerations
LT1767EMS8-1.8#TRPBF offers a 1.8V fixed output. LT1767EMS8E-3.3#PBF provides a 3.3V output in tube packaging. LT1767EMS8-2.5#TRPBF is the non-exposed pad version of the same electrical specification.
