KIA3502P

BIPOLAR LINEAR INTEGRATED CIRCUIT

Revision No : 0

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.
