The CL8801 is designed to drive a long string of inexpensive, low current LEDs directly from the AC mains. A basic driver circuit consists of the CL8801, four resistors, and a bridge rectifier. Two to four additional components are optional for various levels of transient protection. No capacitors, EMI filters, or power factor correction circuits are needed. A string of series/parallel LEDs is tapped at four locations. Four linear current regulators sink current at each tap and are sequentially turned on and off, tracking the input sine wave voltage.
