MP3362 Single-String, 3V Minimum VIN, 36V VOUT, Boost LED Driver DESCRIPTION The MP3362 is a fixed-frequency converter ideal for low-current and high-current boost applications. The low 0.2V feedback voltage offers higher efficiency in white LED driver applications. The MP3362 regulates the output voltage up to 36V with efficiency as high as 95%. Current mode regulation and external compensation components allow the MP3362 control loop to be optimized across a wide variety of input voltages. The MP3362 supports analog dimming and PWM dimming on the same pin. A <2kHz input dimming frequency initiates PWM dimming, while an >5kHz input initiates analog dimming.
