Function
Equivalent circuit
Sets the PWM oscillator frequency.
Insert a capacitor between this pin and ground.
The PWM oscillator frequency is set to about 34 kHz
when a 680 pF capacitor is used.

Frequency characteristics correction for the current
control circuit.
Insert a capacitor (about 0.01 to 0.1 μF) between this pin
and ground.
The output duty is determined by comparing the voltage
on this pin to the PWM oscillator waveform.
