CS1616-FZZ

Overview

The CS1616-FZZ is a single-output AC-DC offline switcher IC designed for LED lighting applications. It supports flyback, buck, and boost topologies with an operating frequency range of 6 kHz to 200 kHz. The device features triac dimming capability and operates within a supply voltage range of 11 V to 17 V. It is housed in a 16-TSSOP package and functions across a temperature range of -40°C to +125°C TJ.

Feature Summary

• Supports flyback, step-down (buck), and step-up (boost) converter topologies
• Integrated triac dimming functionality for compatible dimmer switches
• Single output configuration for direct LED string driving

Applications

• General LED lighting systems
• Industrial control lighting applications
• Offline AC-DC power supplies for solid-state lamps

Procurement Notes

This component is officially listed as End-of-Life (EOL). Availability is restricted or non-existent through standard distribution channels. Verify current stock status with authorized distributors and consider obsolescence management strategies for existing designs.

Selection Notes

Select this part for designs requiring integrated triac dimming and multi-topology flexibility in a compact TSSOP package. Ensure the application voltage and thermal requirements align with the specified 11V-17V supply range and -40°C to +125°C operating temperature limits.

Part Context

The CS1616-FZZ belongs to the Cirrus Logic CS161x series of LED driver ICs. These devices are engineered for cost-effective, high-performance lighting solutions. The FZZ suffix specifically denotes the 16-TSSOP surface-mount package variant within this product family.

Replacement Considerations

The CS1616-FSZR is a documented substitute part number within the same series, offering identical electrical specifications but utilizing a 16-SOIC package instead of the TSSOP form factor.
