Description

The new generation CoolSET™-F3 provides Active Burst Mode
to reach the lowest Standby Power Requirements <100mW at no
load. As the controller is always active during Active Burst
Mode, there is an immediate response on load jumps without any
black out in the SMPS. In Active Burst Mode the ripple of the
output voltage can be reduced <1%. Furthermore, to increase the
robustness and safety of the system, the device enters into Auto
Restart Mode in the cases of Overtemperature, VCC
Overvoltage, Output Open Loop or Overload and VCC
Undervoltage. By means of the internal precise peak current
limitation, the dimension of the transformer and the secondary
diode can be lowered which leads to more cost efficiency. An
adjustable blanking window prevents the IC from entering Auto
Restart or Active Burst Mode unintentionally during high load
jumps. The CoolSET™-F3 family consists a wide power class
range of products for various applications.

1.5 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 PWM­Comparator 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.

Pin Configuration and Functionality

Drain (Drain of integrated Depl. CoolMOS™)

Pin Drain is the connection to the Drain of the internal Depl.
CoolMOS

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.
