Description
The totem-pole output driver for driving the power MOSFET.
Power supply.
No connection.
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 provides current information for current-mode control.
No connection.
No connection.
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.
