Pin Description
+V
IN
–
This pin is the input to the internal linear regulator.
V
ON
–
The voltage applied to this pin by a resistor voltage divider
from +V
IN
controls the on time (pulse width) of the gate output.
V
DD
–
This pin is the output of the internal linear regulator and the
supply pin for the internal circuits. It must be bypassed with a low
ESR capacitor to provide a low impedance path for the gate drive
and be capable of storing sufficient energy so that the voltage does
not decay below the UVLO threshold during the time when the
input voltage is below the minimum required by the regulator.
AGND –
This pin is the common connection for analog circuits.
GATE –
This pin is the output for driving the gate of an external N-
channel MOSFET.
PGND –
This is the common connection for the GATE drive circuit.
NS –
This pin is the negative terminal of the differential sense
feedback circuit.
PS –
This pin is the positive terminal of the differential sense
feedback circuit.
