C1

C2

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.

15

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.

16

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.

17

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.

18

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.
