Procurement Notes
Verify the current product status before procurement, as the CS1680-FZZR is listed as obsolete or end-of-life in multiple distributor records. Confirm availability through authorized channels or check for valid replacement part numbers if active sourcing is required. Ensure that the specific ordering suffix matches the required package and tape/reel specifications documented in official Cirrus Logic datasheets.
Selection Notes
Select this component for designs requiring dedicated Triac dimming control in low-voltage LED applications. The wide operating temperature range suits various environmental conditions. Verify compatibility with the target flyback or buck-boost topology and ensure the 16-pin TSSOP footprint fits the PCB layout constraints. Check input voltage requirements against the 11 V to 17 V operational window.
Part Context
The CS1680-FZZR belongs to the Cirrus Logic family of LED lighting drivers and interface ICs. It is manufactured by Cirrus Logic Inc., a supplier known for analog and mixed-signal integrated circuits. This specific model is categorized under power management ICs and LED drivers, distinct from the company's primary audio processing products.
Replacement Considerations
