Soft start capacitor connection pin. The pin voltage determines the phase of soft
start, normal mode.
Timing capacitor connection pin. The timing capacitor is charged and discharged
to generate the sawtooth waveform that determines the oscillation frequency in
the internal oscillator block.
Soft start resistor connection pin. The soft start resistor value determines the initial
preheating switching frequency during soft start mode.
Input to the protection circuit. If the pin voltage is lower than 2V, the output of the
gate driver is inhibited.
The ground potential of all the pins.
The output of a high-current power driver capable of driving the gate of a power
MOSFET
The output of a high-current power driver capable of driving the gate of a power
MOSFET.
The logic and control power supply connection.
