CL8801 - Sequential Linear LED Driver

General Description

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 CL8801, four resistors and a bridge rectifier.

Two to four additional components are optional for various levels of transient protection.

Key Features

  • Minimal Component Count  (Base Configuration: CL8801 + Four Resistors + Diode Bridge).
  • No Magnetics, No Capacitors.
  • Up to 7.5W Output (13W with Heat Sink).
  • >110 Lm/W using Efficient LEDs.
  • 85% Typical Electrical Efficiency.
  • >0.95 Power Factor.
