MP3362GJ
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 pensation ponents 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 <2k Hz input dimming frequency initiates PWM dimming, while an >5k Hz input initiates analog dimming.
Soft start, cycle-by-cycle current limiting, and input under-voltage 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.
