Description
The IR2167 is a fully integrated, fully protected 600V ballast control IC designed to
drive all types of fluorescent lamps. PFC circuitry provides for high PF, low THD and
DC Bus regulation. Externally programmable features such as preheat time & fre-
quency, ignition ramp characteristics, and running mode operating frequency provide a
high degree of flexibility for the ballast design engineer. Comprehensive protection
features such as protection from failure of a lamp to strike, filament failures, low AC
line conditions, thermal overload, or lamp failure during normal operation, as well as
an automatic restart function, have been included in the design. The heart of the
ballast control section is a variable frequency oscillator with externally programmmable
deadtime. Precise control of a 50% duty cycle is accomplished using a T-flip-flop.

Note 2:
Note 3:
Sufficient current should be supplied to the VCC pin to keep the internal 15.6V zener clamp diode on this pin
regulating its voltage.
Due to the fact that the RT pin is a voltage-controlled current source, the total RT pin current is the sum of all
of the parallel current sources connected to that pin. During the preheat mode, the total current flowing out
of the RT pin consists of the RPH pin current plus the current due to the RT resistor. During the run mode, the
total RT pin current consists of the RUN pin current plus the current due to the RT resistor.
