Functional Pin Descriptions
RT
This pin provides oscillator switching frequency adjustment.
By placing a resistor (R
T
) from this pin to GND, the nominal
200kHz switching frequency is increased according to the
following equation:
Conversely, connecting a pull-up resistor (R
T
) from this pin
to V
CC
reduces the switching frequency according to the
following equation:
