RT

Oscillator Switching frequency pin. Connecting an external resistor from this pin to ground the

switching frequency is increased according to the equation:

fS

= 200kHz +

⋅ 106

RT

(KΩ)

Connecting the resistor from this pin and the Vcc the Switching frequency is reduced

according to the equation:

fS

= 200kHz −

⋅ 107

RT

(KΩ)

If the pin is not connected the switching frequency is 200kHz.
