EVQ3362-J-00A

EVQ3362-J-00A is a single-string, 3V VIN-MIN, 36V VOUT boost LED driver evaluation board is designed for MPQ3362, a boost LED driver that is well suited for low-to-high current boost applications. The device’s low 0.2V feedback voltage offers higher efficiency in white LED driver applications. The MPQ3362 regulates the output voltage up to 36V, with up to 95% efficiency. Current mode regulation and external compensation components allow the MPQ3362 control loop to be optimized across a wide input voltage range. A <lt/>2KHz input dimming frequency initiates PWM dimming, while a <gt/>5KHz input dimming frequency initiates analogue dimming. Soft start, 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 under overload conditions. It is available in a TSOT23-8 package. Application automotive display backlighting, medium-sized LCD backlighting and general lighting.
