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.
