CS1613A-FSZ

Overview

The CS1613A-FSZ is an AC/DC offline switcher IC designed for LED lighting applications. It supports Buck and Boost topologies with Triac dimming capability. The device operates within a supply voltage range of 11V to 17V and features a switching frequency of 6kHz to 200kHz. It is housed in a 16-SOIC package and functions at temperatures from -40°C to +125°C TJ.

Feature Summary

• Supports AC/DC offline switching with integrated Triac dimming functionality
• Compatible with step-down (Buck) and step-up (Boost) converter topologies
• Designed for single-output LED driver applications

Applications

• LED lighting systems requiring offline AC/DC conversion
• Dimmable LED fixtures utilizing Triac control
• Buck or Boost topology LED driver designs

Procurement Notes

This component is officially classified as obsolete by the manufacturer. Availability is restricted, and sourcing may require verification through authorized distributors or secondary market channels. Procurement should confirm current stock status and authenticity due to the end-of-life designation.

Selection Notes

Select this part for legacy designs requiring specific Cirrus Logic AC/DC offline switching with Triac dimming. Verify compatibility with existing Buck or Boost circuit architectures. Ensure thermal management meets the specified junction temperature range given the SOIC-16 package constraints.

Part Context

The CS1613A-FSZ belongs to the CS1613 series of LED drivers from Cirrus Logic. It shares functional similarities with related models like the CS1613 and CS1615, focusing on efficient AC/DC power conversion for solid-state lighting applications using standard surface-mount packaging.

Replacement Considerations

No public confirmed substitute part numbers are available. As the device is obsolete, engineers must evaluate alternative AC/DC LED driver ICs with compatible Buck/Boost topologies and Triac dimming support.
