EVQ3362-J-00A

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.
