    CYT1001A/B/D

    product manual

    CYT1001 is a high-precision linear LED driver chip, which is applied to single-segment architecture. The system structure is simple, no magnetic components, few peripheral components, and the overall solution cost is low.

    CYT1001 uses patented current control and compensation technology, current accuracy can be controlled within 3%, set by external resistors, peak current 60mA. Multiple chips can be used in parallel to increase current output capability.

    CYT1001 has built-in over-temperature and over-voltage automatic current-reducing functions to improve the safety and reliability of the chip.

    The cost is comparable to the RC architecture, but with multiple protection features, it is safer and more reliable.

    CYT1001 is available in ESOP-8, T0252-5, and S0T89-5 packages.
