1.5 Pin Functionality
LED System Driver ICs
ICLS6x Series
Pin Configuration and Functionality
SoftS (soft start, auto restart & frequency jittering control)
The SoftS pi n com bines the soft start function du ring startup a nd the error detection function for Auto Restart
mode. These functions are implemented and can be adjusted by means of an external capacitor at the SoftS pin
connected to ground. This capacitor also provides an adjustable blanking window for high load jumps before the
IC enters Auto Restart mode. In addition, this pin is also used to control the period of frequency jittering under
normal loads.
FB (feedback)
The information on the regulation is provided by the FB pin to the internal protection unit and to the internal PWM
comparator to contr ol th e du ty cycle. In the event of an op en loa d even t, the de vice enters the Flo ating Load
Protection (FLP) mode.
CS (current sense)
The cu rrent sen se pin se nses th e voltag e de veloped o n th e series resis tor inserted into the source of the
integrated depletion CoolMOS™. If CS reaches the internal threshold of the current limit comparator, the driver
output is immed iately switch ed off. The cu rrent infor mation is provided to th e PWM comparator to re alize th e
current mode.
Drain (drain of integrated depletion CoolMOS™)
The drain pin provides the connection to the drain of the internal depletion CoolMOS™.
VCC (power supply)
The VCC pin is the positive supply of the IC. The operating range of the supply is between 10.3 V and 26 V.
GND (ground)
The GND pin is the common ground of the controller.
