Overview
The LT3505EMS8E#TRPBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6 V to 36 V and delivers up to 1.2 A of output current. The device features an adjustable output voltage, a switch frequency range from 200 kHz to 3 MHz, and a typical quiescent current of 2 mA. It is housed in an 8-lead DFN package designed for surface mount installation.
Feature Summary
- Integrates a high-efficiency synchronous buck converter topology within a compact footprint.
- Supports wide input voltage ranges suitable for various industrial power supply architectures.
- Includes internal compensation and soft-start functionality to simplify circuit design.
Applications
- Industrial control systems requiring regulated DC power
- Distributed power supply architectures
- Battery-powered equipment with wide input variations
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component matches the exact part number to avoid pinout or electrical specification mismatches during procurement.
Selection Notes
Select this component for applications requiring a compact solution with adjustable output voltages. Consider the thermal performance of the DFN package under maximum load conditions. Evaluate the required switching frequency against electromagnetic interference constraints for the target environment.
Part Context
This part belongs to the LT3505 series of switching regulators. It shares the core architecture with variants like LT3505IDD but differs in package type and automotive qualification status. The MSOP-EP variant offers similar electrical characteristics with a different mechanical form factor.
Replacement Considerations
LT3505IMS8E provides equivalent electrical performance in an MSOP-EP package. Verify pin compatibility and thermal dissipation requirements before substituting. Check datasheet revisions for any changes in recommended operating conditions.
