Description:

High-Brightness LED Driver Controller

Features

* 4.5V to 42V input voltage range High efficiency (>90%) ±5% LED current accuracy MIC3203: Dither enabled for low EMI MIC3203-1: Dither disabled High-side current sense Dedicated dim

Applications

* The MIC3203 is well suited for lighting applications requiring a wide-input voltage range. The hysteretic control gives good supply rejection and fast response during load transients and PWM dimming. The high-side current sensing and on-chip current-sense amplifier delivers LED current with ±5% acc
