PIN CONFIGURATION
PIN DESCRIPTION
PIN
NAME
FUNCTION
1
PVFB/OVP
Inverting input to the PFC error
amplifier and OVP comparator input.
2
PEAO
PFC error amplifier output and
compensation node
3
PIFB
Senses the inductor current and peak
current sense point of the PFC cycle
by cycle current limit
4
PIFBO
Output of the current sense amplifier.
Placing a capacitor to ground will
average the inductor current.
5
LAMP FB
Inverting input of the lamp error
amplifier, used to sense and regulate
lamp arc current. Also the input node
for dimmable control.
6
LEAO
Output of the lamp current error
transconductance amplifier used for
lamp current loop compensation
7
