Function
Soft switching adjustment pin.
The triangular wave from is form formed by connecting a
capacitor with this pin.
And, the switching of three-phase output is adjusted by
the slope.
4
FC2
Frequency characteristic correction pin 2.
To suppress the oscillation of control system closed loop
of sink-side, connect a capacitor between this pin and
GND.
5
FC1
Frequency characteristic correction pin 1.
To suppress the oscillation of control system closed loop
of source-side, connect a capacitor between this pin and
GND.
6
VOH
Three-phase output high level output pin.
To stabilize the output voltage of this pin, connect a
capacitor between this pin and the VCC pin.
7
VREG
DC voltage (3.3V) output pin.
Connect a capacitor between this pin and GND for
stabilization.
19
VCC
Pin to supply power-supply voltage.
To curb the influence of ripple and noise. The voltage
should be stabilized.
