Hi team,
What is the RT (frequency setting resistor) value for 2.2MHz Fsw using RT variant?
Table 8-2 of the datasheet suggests RT input can be tied to GND. But from Figure 8-7, several k-ohm resister is required to set Fsw 2.2MHz. And from Equation 1, I got 6.1ohm as RT value when Fsw=2.2MHz.
Which one is correct? Can I tie RT pin to GND?
Best regards,
Kurumi
