Version 1.0, 2011-05-19
LED System Driver ICs
ICLS6x Series
Description
ICLS6x Series controllers employ a fixed-frequency operation mode optimized for offline LED lighting. The
integrated constant power function (patented by Infineon Techologies AG) and the frequency jitter enable high
performance without investment of too much effort in stabilization of the system and filtering in terms of EMC.
A wide VCC range up to 26 V is provided by use of BiCMOS technology to cover changes in the auxiliary supply
voltage if a CV/CC regulation is implemented on the secondary side.
Auto Restart Mode is entered in the case of overtemperature, VCC overvoltage, output open loop or overload and
VCC undervoltage. If an open load event occurs, the device enters the so-called Floating Load Protection (FLP)
mode to protect the LED against destruction. The dimensions of the transformer and the secondary diode can be
reduced owing to the internal precise peak current limitation to yield greater cost efficiency.

Pin Functionality
SoftS (soft start, auto restart & frequency jittering control)
The SoftS pin combines the soft start function during startup and 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 control the duty cycle. In the event of an open load event, the device enters the Floating Load
Protection (FLP) mode.
CS (current sense)
The current sense pin senses the voltage developed on the series resistor inserted into the source of the
integrated depletion CoolMOS™. If CS reaches the internal threshold of the current limit comparator, the driver
output is immediately switched off. The current information is provided to the PWM comparator to realize the
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.

Functional Description
All values used in the functional description are typical values. When calculating the worst cases, the
minimium/maximum values listed in Electrical Characteristics on page 24 have to be considered.
3.1
Introduction
For ICLS6x Series controllers, a high voltage startup cell is integrated into the system IC, which is switched off
once the undervoltage lockout-on threshold of 18 V is exceeded. This startup cell is part of the integrated depletion
CoolMOS™. The external startup resistor is no longer necessary as the startup cell is connected to the drain,
resulting in reduced power losses. This increases the efficiency under light load conditions drastically.
The soft start capacitor is also used for providing an adjustable blanking window for high load jumps. The overload
detection function is disabled during this window. With this concept, no further external components are necessary
to adjust the blanking window.
An Auto Restart mode is implemented in the IC to reduce the average power conversion in the event of malfunction
or unsafe operating conditions in the LED drives. This feature increases the system’s robustness and safety, which
would otherwise lead to a destruction of the LED drive. Once the malfunction is corrected, normal operation is
automatically initiated after the next startup phase.
Together with the soft start capacitor, the feedback can also sense a missing load, which leads to rising output
and auxiliary voltages. This triggers the Floating Load Protection (FLP) mode. When feedback falls below 1.35 V,
the Soft Start voltage begins to rise up to a threshold of 4 V (depends on the C4 value) and the IC is switched into
FLP mode.
The precise internal peak current limitation reduces the costs for the transformer and the secondary diode. The
influence of the change in the input voltage on the power limitation can be avoided together with the integrated
Propagation Delay Compensation circuit. Consequently, the maximum power is practically independent of the
input voltage required for wide range LED drives. There is no need for additional oversizing of the LED drives –
e.g., for the transformer or the secondary diode.

Power management of ICLS6x Series controllers
The undervoltage lockout function monitors the external supply voltage VVCC. When the LED drive is connected to
the main line, the internal startup cell is biased and starts to charge the external capacitor CVCC, which is connected
to the VCC pin. The VCC charge current that is provided by the startup cell from the drain pin is 1.05 mA. If VVCC
exceeds the on-threshold VCCon (= 18 V), the bias circuit is switched on. Then the startup cell is switched off by the
undervoltage lockout; therefore no power losses are present due to the connection of the startup cell to the drain
voltage. An hysteresis loop is implemented to avoid uncontrolled ringing at switch-on. Switch-off of the controller
can only take place after the active mode has been entered and VVCC has fallen below 10.3 V.
The maximum current consumption before the controller is activated is about 300 µA.
If VVCC falls below the off-threshold VCCoff (= 10.3 V), the bias circuit is switched off and a power-down reset causes
discharging of the soft-start capacitor CSoftS at pin SoftS via T4 (see Figure 5). This ensures in every startup cycle
that the voltage ramp at the SoftS pin starts at zero.
The bias circuit is switched off if Auto Restart mode is entered. The current consumption is then reduced to 300 µA.
Once the malfunction condition is resolved, this block will then turn back on. The recovery from Auto Restart mode
does not require disconnection of the LED drive from the AC line.

Soft start
At the beginning of the startup phase, the IC provides a soft start period during which it controls the maximum
primary current by means of duty cycle limitation. A capacitor CSofts in combination with the internal pull-up resistor
RSoftS determines the duty cycle until VSoftS exceeds 3.2 V.
When the soft start begins, CSoftS is immediately charged up to approx. 0.8 V by T2. The soft start phase takes
place between 0.8 V and 3.2 V. Above VSoftsS = 3.2 V there is no longer any duty cycle limitation DCmax that is
controlled by the comparator C7 since the comparator C2 blocks the gate G7 (see Figure 7). This maximum
charge current in the very first stage when VSoftS is below 0.8 V is limited to 0.9 mA.

Functional Description
As a consequence of this extra charge stage, there is no delay at the beginning of the startup phase when there
is still no switching. Furthermore, soft start is finished at 3.2 V to have maximum power capability even earlier. The
duty cycles DC1 and DC2 vary according to the mains and the primary inductance of the transformer. The limitation
of the primary current by DC2 is related to VSoftS = 3.2 V. However, DC1 is related to a maximum primary current,
which is limited by the internal current limiting function with CS = 1 V. Therefore the maximum startup phase is
divided into a soft start phase until t1 and a phase from t1 to t2 during which maximum power is provided if
demanded by the FB signal.

Oscillator and Jittering
Gate
The oscillator generates a fixed frequency with frequency jittering of ± 4 % from the fixed frequency (i.e., ± 2.7 kHz
for 67 kHz) at a jittering period TFJ. The switching frequency is fswitch = 67 kHz.
A resistor, a capacitor, a current source and current sink for determining the frequency are integrated. The
charging and discharging current of the implemented oscillator capacitor are internally trimmed in order to achieve
a very accurate switching frequency. The ratio of controlled charge to discharge current is adjusted to reach a
maximum duty cycle limitation of Dmax = 0.75.
Once the soft start period is over and the IC has entered normal mode, the soft start capacitor is charged and
discharged through the internal current source IFJ to generate a triangular waveform with a jittering period TFJ,
which is externally adjustable by means of the soft start capacitor, CSoftS (see Figure 6).
TFJ = k FJ ∗ CSoftS
(1)
where kFJ is a constant = 4 ms/µF.
For example: TFJ = 4 ms if CSoftS = 1µF.

Current limiting
Cycle-by-cycle current limiting realized by the current limit comparator C10 to provide overcurrent detection (see
Figure 10). The source current of the integrated depletion CoolMOS™ is sensed by means of an external sense
resistor RSense. By means of RSense the source current is transformed to a sense voltage VSense which is fed to the
CS pin. If VSense exceeds the internal threshold voltage Vcsth the comparator C10 immediately turns off the gate
drive by resetting the PWM latch FF1. A Propagation Delay Compensation circuit is added to support immediate
shutdown without delay of the integrated internal CoolMOS™ in the case of current limiting. The influence of the
AC input voltage on the maximum output power can be suppressed as a result.
To prevent the current limiting function from causing distortions by leading edge spikes, a Leading Edge Blanking
circuit is integrated into the current sense path for the comparator C10 and the PWM OP.

Leading Edge Blanking
Each time when the integrated internal CoolMOS™ is switched on, a leading edge spike is generated due to the
primary-side capacitances and secondary-side rectifier reverse recovery time. This spike can cause the gate drive
to switch off unintentionally. To avoid premature termination of the switching pulse, this spike is blanked out with
a time constant of tLEB = 220 ns. During this time, the gate drive will not be switched off. This is illustrated in
Figure 11.

Propagation Delay Compensation
In the case of overcurrent detection, switch-off of the integrated internal CoolMOS™ is delayed due to the
propagation delay of the circuit. This delay causes an overshoot of the peak current Ipeak, which depends on the
ratio of dI/dt of the peak current (see Figure 12).

Peak current overshooting
The overshoot of Signal2 is greater than that of Signal1 due to the steeper rising waveform. This change in the
slope varies according to the AC input voltage. A Propagation Delay Compensation circuit is integrated to limit the
overshoot dependency on dI/dt of the rising primary current. This means that the propagation delay between the
time the current sense threshold Vcsth is exceeded and switch-off of the integrated inernal CoolMOS™ is
compensated over temperature within a wide range.

Functional Description
Extremely precise current limiting is now possible.
For example, Ipeak = 0.5 A with RSense = 2 Ω. Without propagation delay compensation the current sense threshold
is set to a static voltage level Vcsth = 1 V. A current ramp of dI/dt = 0.4 A/µs (that means, dVSense/dt = 0.8 V/µs),
and a propagation delay time tPropagation Delay = 180 ns then leads to an Ipeak overshoot of 14.4 %. With propagation
delay compensation the overshoot is only about 2 % (see Figure 13).

3.6
Control Unit
The Control Unit contains the functions for the Auto Restart and Floating Load Protection (FLP) modes. The Auto
Restart mode is combined with an adjustable blanking window, which varies according to the value of the external
soft start capacitor. The IC avoids entering into either of these two modes accidentally by means of this adjustable
blanking window. The window also provides a certain time during which overload detection is delayed. This delay
is useful for applications that normally work with a low current and occasionally require a short duration of high
current.
3.6.1
Adjustable Blanking Window
VSoftS swings between 3.2 V and 3.6 V after the LED drive has settled and S2 is on while S3 is off. This behavior
is due to the frequency jittering function that makes use of the soft start pin. If overload occurs, VFB exceeds 4.5 V.
The Auto Restart mode cannot be entered as the gate G5 is still blocked by the comparator C3. However, after
VFB has exceeded 4.5 V, the switch S2 is opened and S3 is closed. The external soft start capacitor can then be
further charged by the integrated pull-up resistor RSoftS through the switch S3. The comparator C3 releases the
gate G5 once VSoftS has exceeded 4.0 V. This means that Auto Restart mode cannot be entered during the
charging time of the external capacitor CSoftS.

Auto Restart Mode during Startup
The VCC voltage is observed by the comparator C13 if 20.5 V is exceeded. The output of C13 is combined with
both the output of C3, which checks for VSoftS < 4.0 V, and the output of C4, which checks for VFB > 4.5 V.
Therefore, overvoltage detection can only be active during the soft start phase (VSoftS < 4.0 V) and if the FB signal
is outside the operating range (> 4.5 V). This means any small voltage overshoots of VVCC occurring during normal
operation cannot trigger the Auto Restart mode during startup.

In order to ensure system reliability and prevent any false activation, a blanking time is implemented before the IC

Functional Description
The other fault detection function which can result in the Auto Restart mode during startup and has the 8.0 µs
blanking time is for overtemperature detection. This block checks for a junction temperature of higher than 140 °C
for malfunctioning operation.
Once Auto Restart mode is entered, the internal bias is switched off in order to reduce the current consumption of
the IC as much as possible. In this mode, the average current consumption is only 300 µA as the only working
blocks are the reference block and the Undervoltage Lockout (UVLO), which controls the startup cell by switching
on/off at VVCCon/VVCCoff.
As there is no longer a self supply provided by the auxiliary winding, VCC starts to drop. The UVLO switches on
the integrated startup cell when VCC falls below 10.3 V. It continues to charge VCC up to 18 V, at which point it
is switched off again and the IC enters the startup phase.
Once all fault conditions have been removed, the IC automatically powers up as usual with a switching cycle at
the GATE output after the soft start period has elapsed – hence the name Auto Restart mode.
3.6.2.2
Auto Restart Mode during RUN Mode
In the case of overload or open loop, the FB voltage exceeds 4.5 V, which is observed by C4. At this time, the
external soft start capacitor can then be further charged by the integrated pull-up resistor RSoftS via the switch S3
(see Figure 15). If VSoftS exceeds 4.0 V, which is observed by C3, Auto Restart mode during RUN mode is
activated as both inputs of the gate G5 are high.

Auto Restart mode during RUN mode
This charging of the soft start capacitor from 3.2 V ~ 3.6 V to 4.0 V defines a blanking window, which prevents the
system from entering Auto Restart mode during RUN mode unintentionally during large load jumps. In this event,
FB will rise close to 5.0 V for a short duration before the loop regulates FB to less than 4.5 V.
In the case of VCC undervoltage – i.e., VCC falls below 10.3 V, the IC is turned off with the startup cell charging
VCC as described earlier in this section. Once VCC is charged to above 18 V, the IC starts a new startup cycle.
This blanking time window for the Floating Load Protection mode can be forced via the external CSoftS capacitor.
3.6.2.3
Floating Load Protection (FLP)
The circuit starts up as usual, but a missing load leads to a rise in the output and auxiliary voltages.
Reaching the VCC threshold of 24.5 V (voltage divider RD2/R4 and Q2) leads to a reduction in the feedback
voltage and hence to reduced output current pulses in order to keep the output voltage below the maximum rating
of the components. If the feedback level falls below 1.35 V, the Soft Start voltage begins to rise up to a threshold
of 4 V (depends on the C4 value) and the IC is switched into the FLP mode.
