Pin Function Description
Soft start time capacitor connection pin. The pin charge time to Vref determines
The preheating time of lamp.
Timing capacitor connection pin. The timing capacitor is charged and discharged
To generate the sawtooth waveform that determines the oscillator frequency in
the internal oscillator.
Soft start resistor connection pin. The soft start resistor value determines the
initial soft start frequency for preheating.
Input to the protection circuit. If the pin voltage is lower than Vref, the output oh
The output driver1,2 is inhibited.
Ground of the control Section.
Gate drive output. A push pull output stage is able to drive the Power MOSFET
With peak current of 400mA.
