PIN CONFIGURATION
PIN# NAME
FUNCTION
PIN# NAME
FUNCTION
1
EA OUT
PFC Error Amplifier output and
compensation node
2
IA OUT
Output and compensation node of the
PFC average current transconductance
amplifier.
3
I(SINE)
PFC gain modulator input.
4
IA+
Non-inverting input of the PFC
average current transconductance
amplifier and peak current sense point
of the PFC cycle by cycle current limit
comparator.
5
LAMP F.B.
Inverting input of an Error Amplifier
used to sense (and regulate) lamp arc
current. Also the input node for
dimming control.
Output from the Lamp Current Error
Transconductance Amplifier used for
lamp current loop compensation
6
LFB OUT
7
R(SET)
External resistor which sets oscillator
F
MAX
, and R(X)/C(X) charging current
PIN DESCRIPTION
8
R(T)C(T)
Oscillator timing components
9
INTERRUPT Input used for lamp-out detection and
restart. A voltage greater than 7.5 volts
resets the chip and causes a restart
after a programmable interval.
10
R(X)/C(X)
Sets the timing for the preheat,
dimming lockout, and interrupt

P GND
Ground
Power ground for the IC
13
OUT B
Ballast MOSFET drive output
14
OUT A
Ballast MOSFET drive output
15
PFC OUT
