Description of pins and cautions on layout of board
1) VCC1 (Input-side power supply pin)
The VCC1 pin is a power supply pin on the input side. To suppress voltage fluctuations due to the current to drive internal
transformers, connect a bypass capacitor between the VCC1 and the GND1 pins.
2) GND1 (Input-side ground pin)
The GND1 pin is a ground pin on the input side.
3) VCC2 (Output-side positive power supply pin)
The VCC2 pin is a power supply pin on the output side. To reduce voltage fluctuations due to OUT pin output current,
connect a bypass capacitor between the VCC2 and the GND2 pins.
4) GND2 (Output-side ground pin)
The GND2 pin is a ground pin on the output side.
5) INA, INB (Control input terminal)
The INA and INB pins are used to determine output logic.

6) OUT (Output pin)
The OUT pin is used to drive the gate of a power device.
7) MC (Output pin for Miller Clamp)
The MC pin is for preventing the increase in gate voltage due to the Miller current of the power device connected to the
OUT pin. If the Miller Clamp function is not used, short-circuit the MC pin to the GND2 pin.
8) XFLT (Fault signal output pin)
The XFLT pin is an open drain pin used to output a fault signal when a fault occurs (i.e., when the Under-voltage Lockout
function (UVLO1) is activated).
