LT1506IR-3.3#TRPBF

Overview

The LT1506IR-3.3#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc., housed in an 8-pin DDPAK package with a thermal tab. It provides a fixed 3.3V output at up to 4.5A. The device operates from a 4V to 15V input range with a 500kHz switching frequency. Internal features include a 4.5A power switch, soft-start, and current limit protection.

Feature Summary

Synchronous rectification architecture for high efficiency
Integrated 4.5A power switch
Fixed 3.3V output voltage option
Built-in soft-start and current limiting

Applications

Point-of-load regulation for digital logic
Battery-powered equipment power supplies
General-purpose DC/DC conversion

Procurement Notes

Verify the exact suffix #TRPBF indicates tape-and-reel packaging with lead-free composition. Confirm the IR temperature grade matches your operational requirements. Cross-reference the manufacturer's latest datasheet for pinout and thermal pad specifications before finalizing procurement.

Selection Notes

Select this component when a fixed 3.3V rail is required with moderate current demands up to 4.5A. The synchronous design offers better efficiency than non-synchronous alternatives. Ensure the input voltage stays within the 4V to 15V window for optimal performance.

Part Context

This part belongs to the LT1506 family of monolithic buck regulators. It is functionally similar to the LT1374 but optimized for lower input voltages. The series includes adjustable and fixed voltage variants packaged in D2PAK or DDPAK formats.
