MPQ3362-AEC1

Single-String, 3V V_IN-MIN, 36V V_OUTBoost LED Driver, AEC1-Q100

New

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.

Advantages Include:

Wide input voltage range and high peak current
Internal power switch and high efficiency
Analog dimming and PWM dimming
Good circuit protection and AECQ-100 available
