Description
Equivalent circuit
Sets the PWM oscillator frequency.
Connect a capacitor between this pin and
ground.
A capacitance of 1800 pF for C sets the
frequency to approximately 37 kHz.

Current control circuit frequency characteri-
stics correction.
Insert a capacitor (on the order of 0.01 to
0.1 μF) between this pin and ground.
The output duty is determined by the ratio of
the voltage on this pin and the PWM
oscillator waveform.

FG filter connection
If noise on the FG signal is a problem, insert
a capacitor (under about 2200 pF) between
this pin and ground.

Sets the operating time of the constraint
protection circuit and also sets the initial
reset pulse.
A protection operating time of about 8
seconds can be set by connecting a
capacitor (about 0.068 μF) between this pin
and ground. If the protection circuit is not
used, connect a capacitor and resistor
(about 4700 pF, 220 k
) in parallel between
this pin and ground.
