    Applications

    • 120VAC, Up to 10W LED Lighting
    • Residential and Commercial Lighting

    Design Notes

    • Channel-to-channel current matching sets backlight uniformity; check the matching spec at the current you will actually run.
    • In boost topologies the OVP threshold must clear the worst-case forward voltage of the longest string, including temperature and binning spread.
    • Keep PWM dimming above 200 Hz to stay clear of visible flicker, and away from the audio band if the product has a speaker.
    • Size the inductor and output capacitor for the string current ripple, not the total LED current.
