Note 1. A flyback supply voltage of > 50V up to 60V i allowed in application. A 220nF capacitor in series with a 22 resistor (depending on IO and the inductance of the coil) has to be connected between Pin9 and GND. The decoupling capacitor of VFB has to be connected between Pin8 and Pin4. The supply voltage line must have a resistance of 33. Note 5. The linearity error is measured without S-correction and based on the same measurement priinciple as performed on the screen. The measuring method is as follows: Divide the output signal I5 - I9 (VRM) into 22 equal parts ranging from 1 to 22 inclusive. measure the value of two succeeding parts called one block starting with 2 and 3 (block 1) and ending with 20 an 21 (block 10). Thus part 1 and 22 are unused. The equations for lineariy error for adjacent blocks (LEAB) and linearity error for not adjacent blocks (LENAB) are given below: ak - a(k + 1) amax - amin LEAB = ; LENAB = aavg aavg Note 6. Referenced to VP. Note 7. The V values within formulae relate to voltages at or across the relative pin numbers, i.e. V9-5/V1-2 = voltage value across Pin9 and Pin5 divided by voltage value across Pin1 and Pin2. Note 8. V3-5 AC short-circuited.
