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.
