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 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. Voltage across each regulator is minimized
when conducting, providing high efficiency. Output current
at each tap is individually resistor-adjustable. Cross-
regulation, as the CL8801 switches from one regulator to
the next, 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.
