USING THE R
T
PIN
The triangular waves, as shown in Figure 1, act to set the oscillator frequency by charging and discharging the
capacitor connected to the C
T
pin using the current value of the resistor connected to the R
T
pin.
In addition, when voltage level V
REF
/2 is output to external circuits from the R
T
pin, care must be taken in making
the external circuit connections to adjust for the fact that I
1
is increased by the value of the current I
2
to the
external circuits in determining the oscillator frequency (see Figure 2).
