LT1506CR-3.3#PBF

Overview

The LT1506CR-3.3#PBF is a monolithic synchronous step-down switching regulator manufactured by Analog Devices Inc., housed in an 8-pin (7+Tab) DDPAK package. It operates with an input voltage range of 4V to 15V and provides a fixed output voltage of 3.3V at up to 4.5A. The device integrates a 4.5A power switch, oscillator, control logic, and synchronous rectification circuitry on a single die. Designed for lower input voltage applications compared to the LT1374, it functions as a direct replacement with optimized performance characteristics.

Feature Summary

Integrates a high-current 4.5A internal power switch and synchronous rectifier for efficient buck conversion
Optimized for low input voltage operation within the 4V to 15V range
Includes complete oscillator, control, and logic circuitry on a single monolithic die

Applications

Point-of-load regulation for digital circuits requiring 3.3V supply
Battery-powered systems operating between 4V and 15V input
General-purpose DC-to-DC step-down conversion in compact form factors

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements before soldering. Cross-reference ordering suffixes carefully to match exact specifications.

Selection Notes

Select this component when a fixed 3.3V output is required from a 4V to 15V source with currents up to 4.5A. Consider the DDPAK package for thermal management needs. Evaluate compatibility with existing PCB layouts designed for the LT1374 footprint if upgrading from that platform.

Part Context

This part belongs to the LT1506 family of switching regulators. It serves as a functional equivalent to the LT1374 but is specifically engineered for lower input voltage ranges. The synchronous design improves efficiency over traditional non-synchronous buck converters.
