MPQ3362-AEC1

MPQ3362-AEC1

Single-String, 3V V_{IN_MIN}, 36V V_OUTBoost LED Driver, AEC-Q100

Datasheet

Description

The MPQ3362 is a fixed-frequency driver, which makes it well-suited for low-current and high-current boost applications. The low 0.2V feedback voltage offers higher efficiency in white LED driver applications.

The device regulates the output voltage up to 36V with efficiency as high as 95%. Current mode regulation and external compensation components allow the MPQ3362 control loop to be optimized across a wide variety of input voltages.

The MPQ3362 supports analog dimming and PWM dimming on the same pin. A <2kHz input dimming frequency activates PWM dimming, while a >5kHz input dimming frequency activates analog dimming.

Soft start, cycle-by-cycle current limiting, and input under-voltage lockout (UVLO) protections prevent sensitive external circuitry from being damaged or overstressed during start-up or potential overload current conditions.

The MPQ3362 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 (V_FB) offers higher efficiency in white LED (WLED) driver applications. It can regulate the output voltage (V_OUT) 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 (V_IN) 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 V_IN 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.
