Function
Power supply.
NC pin.
Current sense. It senses the voltage across a sensed resistor. To provide over-current
protection, PWM output is disabled if the voltage exceeds an internal threshold. This pin
also provides current information for current-mode control.
NC pin.
NC pin.
Feedback. The FB pin provides feedback information to the internal PWM comparator.
This feedback is used to control the duty cycle. When no feedback is provided, this pin is
left open.
Ground.
