General Description
The CL8800 is designed to drive a long string of inexpensive, low
current LEDs directly from the AC mains. A basic driver circuit
consists of the CL8800, six 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 six locations. Six linear
current regulators sink current at each tap and are sequentially
turned on and off, tracking the input sine wave voltage. Voltage
across each regulator is minimized when conducting, providing
high efficiency. Output current at each tap is individually resistor-
adjustable. Cross-regulation, as the CL8800 switches from one
regulator to another, provides smooth transitions. The current
waveform can be tailored to optimize for input voltage range,
line/load regulation, output power/current, efficiency, power
factor, THD, dimmer compatibility, and LED utilization.
With the addition of an RC network, the driver is compatible with
phase dimming.
