MP3324 4-16V, 100mA, 8CH LED Driver QFN-24

The MPS MP3324 is a LED Driver. It operates from a 4 V to 16 V input, is rated for 100 mA and drives 8 LED strings. It is supplied in a QFN-24 package.

The MP3324 is an 8-channel white LED (WLED) driver that operates from a wide 4V to 16V input voltage (VIN) range.

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.
