Pin Configuration and Functionality

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 integrated Depl.
CoolMOS™. 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.
Drain (Drain of integrated Depl. CoolMOS™)
Pin Drain is the connection to the Drain of the internal Depl.

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.
