DUAL DIMMING, EXTENDED TEMPEERATURE CCFL INVERTER MODULE
PRELIMINARY DATASHEET
WIDE RANGE DIMMING FUNCTION
Dimming can be controlled by a DC voltage (like a voltage
output DAC) or by a PWM signal (5V logic level PWM signal
from a micro controller). The PWM signal should be 400Hz to
4kHz, 0V to 5V, 0% to 100% duty cycle.

AMPLITUDE BOOST FUNCTION
The Boost Function Control signal levels are the same as
the Dimming Control. Less than 0.5V provides 4mA
maximum lamp current while 4.5V on Boost provides “max
boost” with a max lamp current of 9mA. Please note that
these maximum lamp current levels are protected by the on-
board thermister which limits the maximum lamp current
automatically as a function of temperature as seen in Figure
9.
