Half bridge control IC for CCFL backlighting
Table 1. Quick reference data.
T amb = 25 ° C; V VDD = 12 V; R IREF = 33 k ? ; V EN = V VDD and CPWM connected to a capacitor, unless
otherwise speci?ed. All voltages are measured with respect to signal ground (SGND, pin 10). SGND
and PGND connected together. Currents are positive when ?owing into the IC.

Given frequency is switching frequency of GL and GH. Sawtooth frequency on CF pin is twice as high.
Can be set by external capacitor
PWMD is active low: A low level on the PWMD pin corresponds with lamps-on. Example: δ PWM = 20 %
means PWMD is during 20 % of each cycle low and the lamps are 20 % of the time on, resulting in a light
output of 20 %.
