S6510 F Semiconductor SIMPLE BALLAST CONTROLLER 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. Features • • • • • • • No lamp protection Low Start up & Operating Current Internal Soft Start Flexible Soft Start Frequency Trimmed 1.5% internal Reference Under Voltage Lock Out with Hysteresis High Current Totem Pole Gate Drive Ordering Information Type NO.
