Overview
The LT1506IS8-3.3#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc., operating at a fixed 500kHz frequency. It provides a fixed 3.3V output with a maximum current capacity of 4.5A. The device accepts an input voltage range from 4V to 15V and utilizes a compact SOIC-8 surface-mount package. This monolithic buck mode regulator integrates the power switch, oscillator, and control logic for efficient DC-to-DC conversion.
Feature Summary
- Synchronous rectification architecture for high efficiency
- Integrated 4.5A power switch
- Fixed 3.3V output voltage option
- Compact SOIC-8 package design
Applications
- Point-of-load regulation for digital circuits
- Battery-powered equipment power management
- General-purpose DC-DC conversion in industrial systems
Procurement Notes
Verify the specific suffix IS8 against official datasheets to confirm the package type and temperature rating. Ensure the #TRPBF designation matches the required tape-and-reel packaging format. Cross-reference the manufacturer part number directly with Analog Devices documentation to avoid counterfeit components or incorrect revisions.
Selection Notes
Select this component when a fixed 3.3V rail is required from a 4V to 15V source. The 4.5A output capability suits moderate load applications. Consider the SOIC-8 footprint for board space constraints. Verify thermal requirements for the specific PCB layout to ensure stable operation under full load conditions.
Part Context
This part belongs to the LT1506 family of synchronous buck regulators. It serves as a lower-input-voltage alternative to the LT1374, optimized for inputs starting at 4V rather than 5.5V. The series offers robust performance for general-purpose power management tasks requiring high current density.

FAQ
What is the primary difference between the LT1506 and LT1374?
The LT1506 is optimized for lower input voltages, operating from 4V to 15V, whereas the LT1374 operates from 5.5V to 25V.
Does the LT1506IS8-3.3 support adjustable output voltage?
No, the -3.3 suffix indicates a fixed 3.3V output configuration.
