S6510P
SIMPLE BALLAST CONTROLLER
F
Description
The device provides simple and performance electronics ballast control function for the half
bridge L/C resonant inverter. This device is optimized for electronics ballast requiring a
minimum board area, reduced component count and low power dissipation.
Internal soft start circuitry eliminates the need for an external soft start PTC resistor.
The initial soft start frequency and soft start time can be easily adjusted depending on the
types of lamp. Prevent burning out of switches in no lamp condition. Internal 18V regulator
clamps Vcc line of supply voltage for eliminating an external zener diode.

Pin Name
Pin Function Description
1 Cs
Soft start time capacitor connection pin. The pin charge time to Vref determines
The preheating time of lamp.
2 C
T
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.
3 Rs
Soft start resistor connection pin. The soft start resistor value determines the
initial soft start frequency for preheating.
4 Ldet
Input to the protection circuit. If the pin voltage is lower than Vref, the output oh
The output driver1,2 is inhibited.
5
GND
Ground of the control Section.
6 OUT2
Gate drive output. A push pull output stage is able to drive the Power MOSFET
With peak current of 400mA.
7 OUT1
Gate drive output. A push pull output stage is able to drive the Power MOSFET
With peak current of 400mA.
