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.
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.

The EVQ3362-J-00A is an evaluation board designed to demonstrate the capabilities of the MPQ3362, a boost LED driver that is ideal for low-to-high current boost applications. The MPQ3362’s low 0.2V feedback voltage (VFB) offers higher efficiency in white LED (WLED) driver applications. It can regulate the output voltage (VOUT) up to 36V, with up to 95% efficiency. Current mode regulation and external compensation optimize the MPQ3362’s control loop across a wide 3V to 36V input voltage (VIN) range.
The MPQ3362 supports analog dimming and pulse-width modulation (PWM) dimming on the EN/DIM pin. A <2kHz input dimming frequency initiates PWM dimming, while a >5kHz input dimming frequency initiates analog dimming.
Soft start (SS), cycle-by-cycle current limiting, and VIN under-voltage lockout (UVLO) prevent the device from overstress or damage. This protects the sensitive external circuitry during start-up and underload/overload conditions. The MPQ3362 is available in a TSOT23-8 package.
