Introduction
Clare's CPC9909 Evaluation Board contains all the
necessary circuitry to demonstrate all the features of
CPC9909 High Brightness (HB), Off-Line LED driver.
The CPC9909 IC architecture includes pulse
frequency modulation (PFM) with a constant
peak-current control scheme. This regulation scheme
is inherently stable, allowing the driver to operate
above 50% duty cycle without open-loop instability or
sub-harmonic oscillations. This greatly increases the
number of LEDs in series that can be driven by the
CPC9909 and by this Evaluation Board.
Linear LED dimming can be achieved either by
adjusting the on-board potentiometer, RA1, or by
adjusting the voltage at the LD pin. In addition, PWM
dimming can be achieved with a user-applied
TTL-level, low frequency, pulse-width-modulated
square wave signal between JP1-1 (GND) and
JP1-2 (connected to the PWMD pin of the CPC9909).

... Please note that in some cases, during turn-off transitions of the external power MOSFET, high current spikes from the external inductor can develop. In this case, the design may require placing a high voltage capacitor, 100nF or higher, between the LED+ and LED- terminals to filter these current spikes. www.clare.com 5 ...
