The QW2032 is a high current accuracy step-down converter designed in continuous current mode for driving the high brightness Light Emitting Diodes(LED). The QW2032 employs patent protected analog dimming LED method to regulate a high accuracy LED current and fine dimming curve. Moreover, this control scheme provides a constant switching frequency in applications. The QW2032 includes anti-stuck function for power-up and open-load check function.

The QW2032 implements frequency jitter for EMI. The QW2032 is available in ESOP-8 package.
