RT:
Connection for the timing resistor which
decides the oscillator frequency. Use a re-
sistor in the range 5.1 k
pin voltage is approx. 0.4 V.
CT:
Connection for the timing capacitor which
decides the oscillator frequency. Use a ca-
pacitor in the range 100 pF to 10 000 pF.
For the oscillator frequency setting, refer
to the "Application Notes, [1] Function
descriptions" section. Use an oscillator fre-
quency in the range 5 kHz to 500 kHz.
DTC:
Connection for a resistor and a capacitor
that set the dead-time and soft start period
of PWM output.
