CL330 - 3-Channel 30mA Linear LED Driver

General Description

The CL330 is designed to drive 3 strings of LEDs at a constant current of 30mA.

Other drivers with currents in the range of 20 - 30mA are available.

The drive current is fixed, with a ±6% tolerance over a VOUT range of 4.0 - 15V.

Key Features

  • ±6.0% current accuracy @ 4.0 -15V.
  • 90V standoff voltage.
  • Separate enable pins for each channel allow for PWM dimming.
  • Over-temperature protection.
  • 8-Lead SOIC (w/Heat Slug) package.

CL330 3-Channel 30mA Linear LED Driver Features ► ±6.0% current accuracy @ 4.0 -15V ► 90V standoff voltage ► Separate enable pins for each channel allow for PWM dimming ► Over-temperature protection ► 8-Lead SOIC (w/Heat Slug) package Applications ► LCD backlighting ► Indicator lamps General Description The CL330 is designed to drive 3 strings of LEDs at a constant current of 30mA. Other drivers with currents in the range of 20 - 30mA are available. The drive current is fixed, with a ±6% tolerance over a VOUT range of 4.0 - 15V. Separate enable pins for each channel allow for PWM dimming, 3-step linear dimming, or individual disconnection of faulty LED strings. Over-temperature protection circuitry shuts down all 3 channels when the nominal die temperature reaches 135°C.
