The totem-pole output driver for driving the power MOSFET.
Power supply.
NC pin.
Current sense input pin. Connected to MOSFET current sensing resistor
node.
A resistor connected between RI and GND sets switching frequency. A
100kΩ resistor Ri results in a 70kHz switching frequency.
NC pin.
Feedback input pin. The PWM duty cycle is determined by voltage level
into this pin and SENSE pin input.
Ground.
