资 源 简 介

The QX9910 is a high efficient LED driver control IC. It is a universal control LED driver and can be configured to operate as a step-up, step-down and step-up/step-down LED driver. The input and output voltage can be extended beyond 450V.  The QX9910 uses a fixed off TIme and 2MHz switching frequency can be achieved. The minimum off TIme can be set by an external capacitor and resistor.  The LED current is programmable and is set from 20mA to 2.0A by an external resistor.
