DESCRIPTION
The Electronic Ballast controller chip has been designed in a bipolar
process. It is housed in a 20-lead dual-in-line plastic package. The
control chip contains the equivalent of two (2) switched mode power
supply control circuits. The first SMPS controller is a DC-to-DC
converter operating in the discontinuous current conduction mode.
It is used as a PFC in the ballast system to provide a DC voltage
step-up function, good AC power factor, low AC current harmonic
distortion, and circuit protection against some types of AC voltage
transients. The PFC uses pulse width modulation to control the
power transfer with an external MOS power transistor. The second
SMPS circuit is a half-bridge oscillator circuit. It converts the DC
output voltage of the PFC into a high frequency AC voltage for
operating lamps. Power transfer in this circuit is controlled by
changing the switch frequency. The half-bridge controller circuit is
capable of driving two external high voltage MOS power transistors
and it has circuits to regulate the lamp current, limit the peak lamp
voltage, and protect the power switches during fault conditions. This
electronic ballast controller circuit has the capability of being used in
a dimming application.
