7VDD
IC Supply Voltage
Nominal voltage is 12V and the Under Voltage Lock Out (UVLO) occurs when
VDD < VDD_UVLO and the IC is turned off.
The IC is turned on whenever VDD > VDD_ON (typ. 11.9V).
The maximum voltage on VDD is 16V.
VDD should be clamped by a zener for protection in the system design. Refer to Table 4 for
more details.
8SW
Switch
PWM gate signal for the switch.
It should be connected to the gate of external MOSFET through a gate resistor.
