TDA8351
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
resistor
(dependent on I
O
and the inductance of the coil) has to be connected between pin 7 and ground. The decoupling
capacitor of V
FB
has to be connected between pin 6 and pin 3. This supply voltage line must have a resistance of
33
(see application circuit Fig.6).
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:
Divide the output signal I

I
7
(V
RM
) into 22 equal parts ranging from 1 to 22 inclusive. Measure the value of two
succeeding parts called one block starting with part 2 and 3 (block 1) and ending with part 20 and 21 (block 10). Thus
part 1 and 22 are unused. The equations for linearity error for adjacent blocks (LEAB) and linearity error for not
adjacent blocks (LENAB) are given below:
