Pin Functionality
BBA (Brownout, extended Blanking time & Auto-
restart enable)
The BBA pin combines the functions of brownout,
extendable blanking time for over load protection and
the external auto-restart enable. The brownout feature
is to stop the switching pulse when the input voltage is
dropped to a preset low level. The extendable blanking
time function is to extend the built-in 20 ms blanking
time for over load protection by adding an external
capacitor to ground. The external auto-restart enable
function is an external access to stop the gate
switching and force the IC to enter auto-restart mode.
It is triggered by pulling the pin voltage to less than
0.4V.
FBB (Feedback & Burst entry control)
The FBB pin combines the feedback function and the
burst entry/exit control. The regulation information is
provided by the FBB pin to the internal Protection Unit
and the internal PWM-Comparator to control the duty
cycle. The FBB-signal is the only control signal in case
of light load at the Active Burst Mode. The burst entry/
exit control provides an access to select the entry/exit
burst mode level.
CS (Current Sense)
The Current Sense pin senses the voltage developed
on the shunt resistor inserted in the source of the
integrated 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.
Drain (Drain of integrated CoolMOS
®
)
Pin Drain is the connection to the Drain of the
integrated CoolMOS
®
.
VCC (Power Supply)
The VCC pin is the positive supply of the IC. The
operating range is between 10.5V and 25V.
GND (Ground)
The GND pin is the ground of the controller.

3.1
Introduction
CoolSET
®
-F3R80 brownout and jitter 800V version
(ICE3AR2280JZ-T) is the enhanced version of the
CoolSET
®
-F3R 650V version (ICE3BRxx65J). It is
particular good for high voltage margin low power
SMPS application such as auxiliary power supply for
PC and server. The major characteristics are that the
IC is developed with 800V CoolMOS
®
with start up cell,
having adjustable brownout feature, running at 100KHz
switching frequency and packed in DIP-7 package. It is
derived from F3R 650V version. Thus most of the good
features are retained. Besides, it includes some
enhanced features and new features.
The
retained
good
features
include
BiCMOS
technology to reduce power consumption and increase
the Vcc voltage range, cycle by cycle current mode
control, built-in 10ms soft start to reduce the stress of
switching elements during start up, built-in 20ms and
extended blanking time for short period of peak power
before entering protection, active burst mode for lowest
standby power and propagation delay compensation
for close power limit between high line and low line,
frequency jittering for low EMI performance, the built-in
auto-restart mode protections for open loop, over load,
Vcc OVP, Vcc under voltage, etc. and also the most
flexible external auto-restart enable, etc.
The enhanced features include narrowing the feedback
voltage swing from 0.5V to 0.3V during burst mode so
that the output voltage ripple can be reduced by 40%,
reduction of the fast voltage fall time of the MOSFET by
increasing the soft turn-on time and addition of 50W
turn-on resistor, faster start up time by optimizing the
Vcc capacitor to 10uF and over temperature protection
with 50°C hysteresis.
The new features include adjustable brownout for
reliable output performance, selectable entry and exit
burst mode so that smaller entry/exit power to burst
mode or even no burst mode is possible and the
propagation delay compensation for burst mode so that
the entry/exit burst mode power is close between high
line and low line.
In summary, the CoolSET
®
F3R80 provides good
voltage margin of MOSFET, lowest standby power,
flexible burst level, reduced output ripple during burst
mode, reliable output with brownout feature, accurate
power limit for both maximum power and burst power,
low EMI with frequency jittering and soft gate drive,
built-in and flexible protections, etc. Therefore,
CoolSET
®
F3R80 is a complete solution for the low
power SMPS application.
3.2
Power Management
Figure 3
Power Management
The Undervoltage Lockout monitors the external
supply voltage V
VCC
. When the SMPS is plugged to the
main line the internal Startup Cell is biased and starts
to charge the external capacitor C
VCC
which is
connected to the VCC pin. This VCC charge current is
controlled to 0.9mA by the Startup Cell. When the V
VCC
exceeds the on-threshold V
CCon
=17V the bias circuit
are switched on. Then the Startup Cell is switched off
by the Undervoltage Lockout and therefore no power
losses present due to the connection of the Startup Cell
to the Drain voltage. To avoid uncontrolled ringing at
switch-on, a hysteresis start up voltage is implemented.
The switch-off of the controller can only take place
when V
VCC
falls below 10.5V after normal operation
was entered. The maximum current consumption
before the controller is activated is about 200mA.
When V
VCC
falls below the off-threshold V
CCoff
=10.5V,
the bias circuit is switched off and the soft start counter
is reset. Thus it ensures that at every startup cycle the
soft start starts at zero.
The internal bias circuit is switched off if Auto Restart
Mode is entered. The current consumption is then
reduced to 320mA.

Once the malfunction condition is removed, this block
will then turn back on. The recovery from Auto Restart
Mode does not require re-cycling the AC line.
When Active Burst Mode is entered, the internal Bias is
switched off most of the time but the Voltage Reference
is kept alive in order to reduce the current consumption
below 620mA.
3.3
Improved Current Mode
Figure 4
Current Mode
Current Mode means the duty cycle is controlled by the
slope of the primary current. This is done by comparing
the FBB signal with the amplified current sense signal.
Figure 5
Pulse Width Modulation
In case the amplified current sense signal exceeds the
FBB signal the on-time t
on
of the driver is finished by
resetting the PWM-Latch (Figure 5).
The primary current is sensed by the external series
resistor R
Sense
inserted in the source of the integrated
CoolMOS
®
. By means of Current Mode regulation, the
secondary output voltage is insensitive to the line
variations. The current waveform slope will change with
the line variation, which controls the duty cycle.
The external R
Sense
allows an individual adjustment of
the maximum source current of the integrated
CoolMOS
®
.
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 T2, the voltage source V1 and a resistor R1
(see Figure 6). Every time the oscillator shuts down for
maximum duty cycle limitation the switch T2 is closed
by V
OSC
. When the oscillator triggers the Gate Driver,
T2 is opened so that the voltage ramp can start.
Figure 6
Improved Current Mode
In case of light load the amplified current ramp is too
small to ensure a stable regulation. In that case the
Voltage Ramp is a well defined signal for the
comparison with the FBB-signal. The duty cycle is then
controlled by the slope of the Voltage Ramp.
By means of the time delay circuit which is triggered by
the inverted V
OSC
signal, the Gate Driver is switched-off
until it reaches approximately 156ns delay time (Figure

till 0% by decreasing V

below that threshold.

Light Load Conditions
3.3.1
PWM-OP
The input of the PWM-OP is applied over the internal
leading edge blanking to the external sense resistor
R
Sense
connected to pin CS. R
Sense
converts the source
current into a sense voltage. The sense voltage is
amplified with a gain of 3.25 by PWM OP. The output
of the PWM-OP is connected to the voltage source V
1
.
The voltage ramp with the superimposed amplified
current signal is fed into the positive inputs of the PWM-
Comparator C8 and the Soft-Start-Comparator (Figure
8).
3.3.2
PWM-Comparator
The PWM-Comparator compares the sensed current
signal of the integrated CoolMOS
®
with the feedback
signal V
FBB
(Figure 8). V
FBB
is created by an external
optocoupler or external transistor in combination with
the internal pull-up resistor R
FB
and provides the load
information of the feedback circuitry. When the
amplified current signal of the integrated CoolMOS
®
exceeds the signal V
FBB
the PWM-Comparator
switches off the Gate Driver.
