need for external soft-start circuit. And the initial pre-
heating 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 ca-
pacitor (Ct).

tection or any required protection like over current
protection can be realized by adding an external
small signal transistor.
