4. The PWM carrier frequency fpwm and the amplitude Apwm are determined by the following

equation.

fpwm =

Vrt

8 Ct1 Rt (Vct1h − Vct1l)

Apwm = 4 Ct1 (Vct1h − Vct1l)

Ct2

However, Ct2 = 4 Ct1

5. As 5 kΩ appears as an internal resistance at TRYIN (pin 6), caution is required when marking

the gain setting.
