SoftS (Soft Start & Auto Restart Control)
This pin combines the function of Soft Start in case of
Start Up and Auto Restart Mode and the controlling of
the Auto Restart Mode in case of an error detection.
FB (Feedback)
The information about the regulation is provided by the
FB Pin to the internal Protection Unit and to the internal
PWM-Comparator to control the duty cycle.
Isense (Current Sense)
The Current Sense pin senses the voltage developed
on the series resistor inserted in the source of the
external Power Switch. When Isense reaches the
internal threshold of the Current Limit Comparator, the
Driver output is disabled. By this mean the Over
Current Detection is realized.
Furthermore the current information is provided for the
PWM-Comparator to realize the Current Mode.
Gate (Driver Output)
The current and slew rate capability of this pin are
suited to drive Power MOSFETs.
VCC (Power supply)
This pin is the positive supply of the IC. The operating
range is between 8.5V and 21V.
To provide overvoltage protection the driver gets
disabled when the voltage becomes higher than 16.5V
during Start up Phase.
GND (Ground)
This pin is the ground of the primary side of the SMPS.
