Pin Configuration and Functionality
1.3
Pin Functionality
SoftS (Soft Start & Auto Restart Control)
The SoftS pin combines the functions of Soft Start
during Start Up and error detection for Auto Restart
Mode. These functions are implemented and can be
adjusted by means of an external capacitor at SoftS to
ground. This capacitor also provides an adjustable
blanking window for high load jumps, before the IC
enters into Auto Restart Mode.
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. The FB-
Signal controls in case of light load the Active Burst
Mode of the controller.
CS (Current Sense)
The Current Sense pin senses the voltage developed
on the series resistor inserted in the source of the
external PowerMOS. If CS reaches the internal
threshold of the Current Limit Comparator, the Driver
output is immediately switched off. Furthermore the
current information is provided for the PWM-
Comparator to realize the Current Mode.
Gate
The Gate pin is the output of the internal driver stage
connected to the Gate of an external PowerMOS.
HV (High Voltage)
The HV pin is connected to the rectified DC input
voltage. It is the input for the integrated 500V Startup
Cell.
VCC (Power supply)
The VCC pin is the positive supply of the IC. The
operating range is between 8.5V and 21V.
GND (Ground)
The GND pin is the ground of the controller.
