Notes
1.
A flyback supply voltage of
>50 V up to 60 V is allowed in application. A 220 nF capacitor in series with
a 22
Ω resistor (dependent on I
o and the inductance of the coil) has to be connected between pin 7 and
ground. The decoupling capacitor of VFB has to be connected between pin 6 and pin 3. The supply voltage
line must have a resistance of 33
Ω.
2.
The linearity error is measured without S-correction and based on the same measurement principle as
performed on the screen. The measuring method is as follows:
