Features

Description

• 8V to 550V Input Voltage Range

• >90% Efficiency

• Stable Operation at >50% Duty Cycle

• Drives Multiple LEDs in Series/Parallel

• Regulated LED Current

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 to

• Linear or PWM Brightness Control Inputs

• Resistor-Programmable Minimum Off-Time

• SOIC-8 RoHS Compliant Package

• Buck or Boost Configuration

550V . 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.

Applications

• Flat-Panel Display RGB Backlighting

• Signage and Decorative LED Lighting

• DC/DC or AC/DC LED Driver Applications

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).
