I/O Description
P Ground
I Feedback input pin. The PWM duty cycle is determined by voltage level into this pin and
SENSE pin input.
I Internal Oscillator frequency setting pin. A resistor connected between RI and GND sets
the PWM frequency.
I Current sense input pin. Connected to MOSFET current sensing resistor node.
P Chip DC power supply pin.
O Totem-pole gate drive output for the power MOSFET.
