Versatile Gate Driver
DESCRIPTIONS
The IP3102 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.
8DIP
8SOP
Internally integrated soft-start circuit eliminated the
need for external soft-start circuit.
FEATURES
Preheating time, preheating frequency, operating
frequency and ignition time can be controlled
separately using external capacitors and resistor.
No lamp protection or any required protection like
over current protection can be realized by adding an
external small signal transistor.
- Internal Soft Start
- Programmable Preheating Frequency
