MP3362GJ-P, LED Driver, DC / DC, 400 kHz, Boost, TSOT-23-8, SMD

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 analogue dimming and PWM dimming on the same pin. A <2KHz input dimming frequency initiates PWM dimming, while an >5KHz input initiates analogue dimming. Soft start, cycle-by-cycle current limiting and input undervoltage lockout prevent overstressing or damaging sensitive external circuitry during start-up or potential overload current conditions. The MP3362 is available in a TSOT23-8 package. Applications include medium-sized LCD backlighting and general lighting.
