Description

The second generation CO OLSET™-F2 provides several
special enhancements t o satisfy the needs for low po wer
standby and protection features. In standby mode
frequency reduction is used to lower the power
consumption and support a stable output voltage in this
mode. The frequency reduction is limited to 21.5 kHz to
avoid audible noise. In case of failure modes like open loop,
overvoltage or overload due to short circuit the device
switches in Auto Rest art Mode which is control led by the
internal protection u nit. By means of the internal precise
peak current limitation the dimension of the transformer and
the secondary diode can be lower which leads to more cost
efficiency.

1.2 Pin Functionality

SoftS (Soft Start & Auto Restart Control)

This pin combines the function of Soft Start i n case of
Start Up and Auto Restart Mod e and the con troll ing of
the Auto Restart Mode in case of an error detection.

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.

Isense (Current Sens e)

The Current Sense pin sense s the voltage develop ed
on the series resistor inserted in the source of the
integrated CoolMOS™. When Isense reaches the
internal threshold of th e Current Limi t Compara tor , the
Driver output is disabled. By this means the Over
Current Detection is realized.

Furthermore the current information is provided for the
PWM-Comparator to realize the Current Mode.

VCC (Power supply)

This pin is the positiv su pply of the IC. The opera ting

during Start Up Phase.

To improve the Current Mode during light load
conditions the amplified current ramp of the PWM-OP
is superimposed on a voltage ramp , which is built by
the switch T
low pass filter composed of R
Figure 7). Every time the oscillator shuts down for max.
duty cycle limitation the switch T2 is closed by V
When the oscillator triggers the Gate Driver T2 is
opened so that the voltage ramp can start.

In case of light load the amplified current ramp is to
small to ensure a stable regulation. In that case the
Voltage Ramp is a well defined signal for the
comparison with the FB-signal. The duty cycle is then
controlled by the slope of the Voltage Ramp.

By means of the C5 Comparator the Gate Driver is
switched-off until the voltage ramp exceeds 0.3V. It
allows the duty cycle to be reduced continou sly till 0%

3.4.2 Frequency Reduction

The frequency of the oscillator is depending on the
voltage at pin FB. The d epe ndence is sho wn in F igu re

lower frequency at light loads thus lowering the
switching losses while maintaining good cross
regulation performan ce and low output ripple. In case
of low power the power consumption of the whole
SMPS can now be reduced very effective. The minimal
reachable frequency is limited to 21.5 kHz to avoid

The overshoot of Signal2 is bigger than of Signal1 due

A propagation delay compensation is integrated to

The driver-stage drives the gate of the CoolMOS™
and is optimized t o minimize EMI and to provide high
circuit efficiency. This is done by reducing the switch on
slope when reaching the CoolMOS™ threshold. This is
achieved by a slope control of the rising edge at the
driver’s output (see Figure 17).

Thus the leading switch on spike is minimized. When
CoolMOS™ is switched off, the falling shape of the
driver is slowed down when reaching 2V to prevent an
overshoot below ground. Furthermore the driver circuit
is designed to eliminate cross conduct ion of the output
stage. At voltages below the undervoltage lockout
threshold V

the gate drive is active low.

3.8 Protection Unit (Auto Re start Mode)

An overload, open loo p and overvoltage detection is
integrated within the Protection Unit. These three
failure modes are latched by an Error-Latch. Additional
thermal shutdown is latched by the Error-Latch. In case
of those failure modes the Error-Latch is set after a
blanking time of 5µs and the C ool MOS™ is shut down.
That blanking pr eve nts the Err or-L atc h fr om di sto rti ons
caused by spikes during operation mode.

Figure 18 shows the Auto Restart Mode in case of
overload or open l oop w ith norma l loa d. T he det ectio n
of open loop or overload is provided by the Comparator
C3, C4 and the AND-gate G2 (see Figure19). The
detection is activa ted by C4 when the vol tage at pin
SoftS exceeds 5.3V. Till this time the IC operates in the
Soft-Start Phase. After this phase the comparator C3
can set the Error-Latch in case of open loop or overload
which leads the feedback voltage V
threshold of 4.8V. After latching VCC decreases till

8.5V and inactivates t he IC. At this time the external

Soft-Start capacitor is discharged by the internal

Total Quality Management

Qualität hat für uns eine umfassende
Bedeutung. Wir wollen allen Ihren
Ansprüchen in der bestmöglichen
Weise gerecht werd en. Es geht uns also
nicht nur um die Produktqualität –
unsere Anstrengungen gelten
gleichermaßen der Lieferqualität und
Logistik, dem Service und Support
sowie allen sonstigen Beratungs- und
Betreuungsleistungen.

Dazu gehört eine bestimmte
Geisteshaltung unserer Mitarbeiter.
Total Quality im Denken und Handeln
gegenüber Kollegen, Lieferanten und
Ihnen, unserem Kunden. Unsere
Leitlinie ist jede Aufgabe mit „Null
Fehlern“ zu lösen – in offener
Sichtweise auch über den eigenen
Arbeitsplatz hinaus – und uns ständig
zu verbesse rn .

Unternehmensweit orientieren wir uns
dabei auch an „top“ (Time Optimized
Processes), um Ihnen durch größere
Schnelligkeit den entscheidenden
Wettbewerbsvorspru ng zu verschaffen.

Geben Sie uns die Chance, hohe
Leistung durch umfassende Qualität zu
beweisen.

Wir werden Sie überzeugen.

Quality takes on an allencompassing
significance at Semiconductor Group.
For us it means living up to each and
every one of your demands in the best
possible way. So we are not only
concerned with product quality. We
direct our efforts equally at quality of
supply and logistics, service and
support, as well as all the other ways in
which we advise and attend to you.

Part of this is t he v ery spec i al att it ude of
our staff. Total Quality in thought and
deed, towards co-workers, suppliers
and you, our customer. Our guideline is
“do everything with zero defects”, in an
open manner that is demonstrated
beyond your immediate workplace, and
to constantly improve.

Throughout the corporation we also
think in terms of Time Optimized
Processes (top), greater speed on our
part to give you that decisive
competitive edge.

Give us the chance to prove the best of
performance through the best of quality
– you will be convinced.
