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.
