The CPC9909 is a low cost, high-efficiency, offline,
high-brightness (HB) LED driver manufactured using
IXYS Integrated Circuits Division’s high voltage
BCDMOS on SOI process. This driver has an internal
regulator that allows it to operate from 8V DC to
550V DC . This wide input operating voltage range
enables the driver to be used in a broad range of HB
LED applications.
The CPC9909 features pulse frequency modulation

(PFM) with a constant peak-current control scheme.
This regulation scheme is inherently stable, allowing
the driver to be operated above 50% duty cycle
without open loop instability or sub-harmonic
oscillations. LED dimming can be implemented by
applying a small DC voltage to the LD pin, or by
applying a low frequency PWM signal to the PWMD
pin.
The CPC9909 is available in a standard 8-lead SOIC
package and a thermally enhanced 8-lead SOIC
package with an exposed thermal pad (EP).
