Typical Application Circuit

Applications

• Solid-State Lighting up to 50 W
• Industrial 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.
