DESCRIPTIONS
The IP3101 provides simple and high performance control functions for the half bridge L/C resonant system, specially electronic ballast . It internally integrated the essential functions of the half bridge L/C resonant system so the conventional system can be realized a minimum board area, small external components and low power dissipation. Internally integrated soft-start circuit eliminated the need for external soft-start circuit. And the initial preheating switching frequency and preheating time can be easily programmable with only one capacitor (preheating frequency capacitor) and one resistor (preheating time capacitor) depending on the types of lamps. Also the normal operating frequency can be easily adjusted by timing resistor (Rt) and timing capacitor (Ct). The cold cathode current can be limited by changing the normal operating frequency to soft-start frequency with an external small signal transistor. No lamp protection or any required protection like over current protection can be realized by adding an external small signal transistor. 8DIP
