Table 1. Necessary CCFL Specifications
Once a CCFL has been struck, the voltage required to maintain
light output falls to approximately 550V
RMS
. Small tubes may
operate on as little as 250V
RMS
. The operating voltage of the
CCFL stays relatively constant, even as the tube’s brightness is
varied.
Although CCFLs typically operate at 550V
RMS,
a higher voltage
is required initially to light up the tube.

The maximum root-mean-square AC current through a CCFL is
almost always 5mA

No DC current is allowed through any
CCFL.

The minimum DC input voltage to the MAX1610/MAX1611 circuit
determines the turns ratio required for the DC-AC conversion
transformer. Decreasing the minimum input voltage increases
the size of the transformer required for a given output power.
