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
2. The linearity error is measured without S-correction and based on the same measurement principle as performed on
3. Referenced to V
4. The V values within formulae relate to voltages at or across relative pin numbers, i.e. V
5. V
6. Frequency response V
7. At V

the screen. The measuring method is as follows:
Divide the output signal I
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:
pins 9 and 5 divided by voltage value across pins 1 and 2.
