■ SETTING THE TRIANGULAR WAVE OSCILLATION FREQUENCY
The triangular wave oscillation frequency can be set by connecting a timing resistor (RT ) to the RT terminal (pin
11) and a timing capacitor (CT) to the CT terminal (pin 12).
Triangular wave oscillation frequency : fOSC
680000
fOSC (kHz) =: _{CT (pF) × RT (kΩ)}
