Overview
The LT1767EMS8#TRPBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates at a fixed switching frequency of 1.25MHz and supports an input voltage range from 3V to 25V. The device provides a single adjustable output with a maximum current capacity of 1.2A. It utilizes current mode control architecture to ensure fast transient response and loop stability. The component is housed in an 8-lead MSOP package and is rated for operation within a junction temperature range of -40°C to +125°C.
Feature Summary
- Integrates a high-efficiency internal power switch and complete control circuitry for high-frequency operation.
- Employs current mode control topology to deliver rapid transient response and stable regulation.
- Supports both buck and SEPIC conversion topologies for flexible input-output voltage configurations.
Applications
- Battery-powered systems requiring efficient step-down conversion
- Industrial equipment power distribution networks
- Portable electronic devices with variable input sources
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the required output configuration and package type exactly to avoid compatibility issues during assembly.
Selection Notes
Select this regulator for designs requiring a compact solution with integrated power switching capabilities. The fixed 1.25MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the load current requirements do not exceed the 1.2A limit under all operating conditions and thermal constraints.
Part Context
This component belongs to the LT1767 series of monolithic DC-to-DC converters. The series is characterized by its ability to function as a synchronous step-down regulator with high efficiency. The EMS8 designation refers to the specific 8-lead MSOP surface-mount package variant used for space-constrained applications.
Replacement Considerations
Direct replacements include other variants within the LT1767 family, such as LT1767EMS8E-2.5 or LT1767EMS8-1.8#TRPBF, provided the fixed output voltage requirements align with the design specifications. Cross-referencing pinouts and thermal characteristics is essential when substituting similar regulators.
