FUNCTION

Buffered output for the 7.5V reference

Inverting input of the lamp error

amplifier, used to sense and regulate

lamp arc current. Also the input node

for dimmable control.

Output of the lamp current error

transconductance amplifier used for

lamp current loop compensation

External resistor which SETS oscillator

FMAX, and RX/CX charging current

Oscillator timing component to set

start frequency

Oscillator timing components

PIN NAME

FUNCTION

7 INTERRUPT Input used for lamp-out detection and

restart. A voltage less than 1V will reset

the IC and cause a restart after a

programmable interval.

8 RX/CX

Sets the timing for preheat and

interrupt.

9 PWDET Lamp output power detection

10 AGND

Analog ground

11 PGND

Power ground.
