General Description

QX9920 is a highly stable and reliable constant-current LED driver with high efficiency.

It is especially suited to drive several high power and high luminance LEDs in series.

QX9920 uses fixed off-time and peak current control mode and its operating frequency can vary up to 1MHz, which not only reduces the dimensions of inductor, capacitor and PCB but also improves efficiency.

Key Features

  • Wide Range Input Voltage:2.5V to 100V.
  • High Efficiency: Up to 90%.
  • Maximum Operating Frequency: 1MHz.
  • UVLO Voltage: 2.5V.
  • Peak Current Sense Voltage: 250mV.
  • Adjustable Luminance With PWM Signal Applied to EN Pin.
  • Adjustable Off-time.
  • Internal Current Sampling Leading Edge Blanking Circuit.
