UC1842: poor programming: if listed above, no need to repeat - but without no Support.... so again: "UC1842"

Part Number: UC1842

The Figure 10 in Datasheet of UC1842 is wrong (see wrong axis scale). Could you please assist with a correct one?

(i.e. 50, 5, printed in between 30 and 40 (3 and 4), resistors started at 3k in diagramm, strictly recommended not under 5k....

If I am rescaling the axis, the formula given at page 4 seems to be fulfilled. Please assist.

Regards Juergen 

  • Hello Juergen,

    Sorry about the confusion. The 5k and 50k label appears to be incorrect. You can use the formula provided on page 4 with resistor values (use resistor value over 5k). We will look into fixing the graph in a future datasheet update.
