KIA3502P
BIPOLAR LINEAR INTEGRATED CIRCUIT
Simple Ballast Controller
DESCRIPTIONS.
The KIA3502 provides simple and high performance control functions
for the half vridge 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. preheating time, preheating frequency, operating
frequency and ignition time can be controlled. separately using
external capacitors and resistor. no lamps protection or any required
protection like over current protection can be realized an external
small signal transistor.
