MPQ3362-AEC1 3-36V VOUT Boost LED Driver TSOT23
The MPS MPQ3362-AEC1 is a VOUT Boost LED Driver. It operates from a 3 V to 36 V input. It is supplied in a TSOT23 package.
The MPQ3362 is a fixed-frequency driver, which makes it well-suited for low-current and high- current boost applications.

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.
