Lzc8650c Ic Datasheet Pdf |best| -

The LZC8650C is a highly efficient, single-stage Power Factor Correction (PFC) controller designed specifically for constant current LED lighting applications. It is widely used in commercial, industrial, and residential LED drivers due to its excellent regulation, low total harmonic distortion (THD), and cost-effective design.

Zero current detection input. Senses the demagnetization signal of the transformer to trigger the next switching cycle. Ground reference pin for all internal control circuitry. GATE
