The QW2036 is a high current accuracy step-down converter designed in continuous current mode for driving the high brightness Light Emitting Diodes(LED). The QW2036 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 QW2036 includes anti-stuck function for power-up and open-load check function.
The QW2036 implements frequency jitter for EMI. The QW2036 is available in SOP-8 package.
