Pin Function
1
Ground
2
Feedback input pin. The PWM duty cycle is determined by voltage level into
this pin and the current-sense signal at Pin 6.
3
Internal Oscillator frequency setting pin. A resistor connected between RI and GND
sets the PWM frequency.
4
Current sense input pin. Connected to MOSFET current sensing resistor node.
5
Chip DC power supply pin.
6
Totem-pole gate drive output for the power MOSFET.
