LT1506CR-SYNC#PBF

Overview

The LT1506CR-SYNC#PBF is a synchronous step-down switching regulator manufactured by Analog Devices (formerly Linear Technology). It delivers a continuous output current of 4.5A with an integrated high-side and low-side MOSFETs. The device operates from an input voltage range of 4V to 15V and provides a fixed 3.3V output. It utilizes a constant frequency, current mode control architecture with a fixed 500kHz switching frequency. The component is housed in an 8-pin D2PAK package with an exposed thermal pad for efficient heat dissipation.

Feature Summary

Integrates high-performance N-channel power switches for high efficiency
Utilizes constant frequency current mode control architecture
Includes internal compensation for stable operation
Features thermal shutdown protection

Applications

Point-of-load regulation for digital signal processors
Power supply stages for embedded systems
Battery-powered equipment requiring high current
Industrial control system power distribution

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required pinout and thermal specifications. Confirm that the manufacturer designation aligns with current Analog Devices inventory records, as legacy Linear Technology part numbers may have updated ordering codes. Cross-reference the package type and lead finish details to match board assembly requirements.

Selection Notes

Select this component when a robust 4.5A synchronous buck solution is required within a compact footprint. The fixed 500kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Ensure the application input voltage remains within the 4V to 15V range and that adequate thermal management is provided via the exposed pad for sustained high-current loads.

Part Context

This part belongs to the LT1506 family of high-current step-down regulators designed for demanding power applications. The series is characterized by its ability to deliver significant output current while maintaining high efficiency across a wide input voltage range. The integration of power switches eliminates the need for external Schottky diodes, simplifying the design and reducing component count.
