DESCRIPTION
P Ground.
I
Feedback input pin. The PWM duty cycle is determined by voltage level
into this pin and SENSE pin input.
Brownout Protection Pin. Connect a resistor divider between this pin
I and bulk capacitor voltage to set the brownout level. If the voltage is
less than threshold voltage, the PWM output will be disabled.
I
Current sense input pin. Connected to MOSFET current sensing resistor
node.
P Power supply.
O The totem-pole output driver for driving the power MOSFET.
