LT1506CS8-3.3#TRPBF

Overview

The LT1506CS8-3.3#TRPBF is a monolithic synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 15V and provides a fixed 3.3V output at up to 4.5A. The device integrates a 4.5A power switch, oscillator, and control logic within an 8-pin SOIC package with an exposed tab for thermal management. It functions at a fixed 500kHz switching frequency, offering high efficiency and compact solution size for low-input-voltage applications.

Feature Summary

Integrates a 4.5A power switch and all necessary control circuitry for synchronous buck operation
Optimized for lower input voltage ranges compared to previous generation regulators
Fixed 500kHz switching frequency enables the use of small external components

Applications

Point-of-load regulation in distributed power systems
Battery-powered equipment requiring efficient step-down conversion
Industrial and telecommunications power supplies

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required tape-and-reel packaging format. Check for RoHS compliance documentation and ensure the part number corresponds to the commercial temperature grade variant intended for your design environment.

Selection Notes

Select this component when a fixed 3.3V output is required from a 4V to 15V input source. It is suitable for designs prioritizing high current capability and compact footprint over adjustable output flexibility. Ensure adequate thermal dissipation is provided due to the integrated power switch characteristics in the SOIC package.

Part Context

This part belongs to the LT1506 family of synchronous step-down regulators. It serves as a functional equivalent to the LT1374 but is specifically optimized for lower input voltage applications, operating down to 4V compared to the LT1374's 5.5V minimum. The device replaces older non-synchronous or higher-voltage rated regulators in modern low-voltage power architectures.
