Description
Input to the comparator of the over-current protection. A resistor senses the switching current
and the resulting voltage is applied to this pin for the cycle-by-cycle current limit. The threshold
voltage for peak current limit is 0.8V.
The power ground and signal ground. A 0.1µF decoupling capacitor placed between V
GND is recommended.
Totem-pole output generates the PWM signal to drive the external power MOSFET. The
clamped gate output voltage is 18V.
Power supply. The threshold voltages for startup and turn-off are 16V and 10V. The startup
current is less than 20µA and the operating current is lower than 4.5mA.
No connect.
High-voltage startup.
