ICE3AR4780CJZ
Off-Line SMPS Current Mode Controller with
integrated 800V CoolMOS® and Startup cell
(brownout & CCM) in DIP-7
Product Highlights
• 800V avalanche rugged CoolMOS® with startup cell
• CCM and DCM operation with slope compensation
• Active Burst Mode to reach the lowest Standby Power 25.5V, the
IC enters into odd skip Auto Restart Mode (Figure 28).
The over temperature protection OTP is sensed inside
the controller IC. The Thermal Shutdown block keeps
on monitoring the junction temperature of the
controller. After detecting a junction temperature higher
than 130°C, the IC will enter into the non switch Auto
Restart mode. The ICE3ARxx80CJZ has also
implemented with a 50°C hysteresis. That means the
IC can only be recovered when the controller junction
temperature is dropped 50°C lower than the over
temperature trigger point (Figure 28).
The external latch enable feature can provide a
flexibility to a customer’s self-defined protection
feature. This function can be triggered by pulling down
the VBRL voltage to < 0.4V. Or it can simply trigger the
base pin of an external transistor, TLE at the BRL pin.
When this function is enabled, it will enter into latch
Version 2.0
40ms
Blanking
Time
Over load and open loop protection
In case of Overload or Open Loop, the VFBB voltage
exceeds 4.5V which will be observed by comparator
C4. Then the built-in blanking time counter starts to
count. When it reaches 40ms, the odd skip Auto
Restart Mode is activated (Figure 29).
3.7.3
Brownout Mode
When the AC input voltage is removed, the voltage at
the bulk capacitor will fall. When it reaches a point that
the system is greater than the system allowed
maximum power, the system may go into over load
protection. However, this kind of protection is not
expected for some of the applications such as auxiliary
power for PC/server system because the output is in
hiccup mode due to over load protection (auto restart
mode). The brownout mode is to eliminate this
phenomenon. The ICE3ARxx80CJZ will sense the

Functional Description
input AC voltage to the BRL pin by an AC hold up circuit
and 2 potential divider resistors.
In some applications, it needs the IC to continue to
work for certain time when AC voltage is disconnected.
After that, the IC will stop working. If the brownout
connection is taping from the bulk capacitor, the delay
time is too short. Therefore, it needs the brown out
detetction at the AC input (Figure 30). The CBR0 is
charged up by AC line voltage through RBO0, which is
then fed to BRL pin through a voltage divider. When the
AC voltage drops, if the BRL pin voltage is lower than
1V for 270μs, the ICE3ARxx80CJZ will go into
brownout mode. If, however, the AC line goes up again,
the BRL voltage will be larger than 1.25V and the
ICE3ARxx80CJZ will leave brown out mode and
recover to normal operation.
The brownout mode is default “ON” during the system
starts up. When the system is powered up, the bulk
capacitor and the Vcc capacitor are charged up at the
same time. When the Vcc voltage is charged to >8V,
the brownout circuit starts to operate (Figure 30). Since
the UVLO is still at low level as the Vcc voltage does
not reach the 17V UVLO “ON” voltage. The NAND gate
G20 will release a low signal to the flip flop FF2 and the
negative output of FF2 will release a high signal. Hence
it is in brownout mode during the system starts up.

Fast AC reset
During normal operation, the ICE3ARxx80CJZ can be
latched by pulling down the BRL voltage below 0.4V for
210μs. There are 2 condtions to reset the latch feature.
The first one is to pull down the Vcc voltage to below
8V. However, the Vcc drop would take quite a long time
if it is by normal AC power down. The second one is to
have a slow rise time of the BRL voltage from 0.4V to
1V for at least 450μs after the BRL pin is pulled down.
This timing can be achieved by the AC recycle. And it
is also called the fast AC reset (Figure 32).

If the brownout feature is not needed, it needs to tie the

Once the system enters the brownout mode, there will
be no switching pulse and the IC enters into another
type auto-restart mode which is similar to the protection
auto-restart mode but the IC will monitor the BRL signal
in each restart cycle (Figure 31).

Case b : latched (dashed line); the timing below 0.4V is
450μs which is larger than 210μs. No latch reset as the
rise time from 0.4V to 1V is 300μs which is less than the
450μs.
Case c : latched and reset (dotted line); the timing
below 0.4V is 710μs which is larger than 210μs. But the
rise time from 0.4V to 1V is 560μs which is larger than
the latch reset blanking time of 450μs.

All voltages are measured with respect to ground (Pin 8). The voltage levels are valid if other ratings are
not violated.

Note:
Absolute Maximum Ratings
Absolute maximum ratings are defined as ratings, which when being exceeded may lead to destruction
of the integrated circuit. For the same reason make sure, that any capacitor that will be connected to pin 7
(VCC) is discharged before assembling the application circuit. Ta=25°C unless otherwise specified.

The electrical characteristics involve the spread of values within the specified supply voltage and junction
temperature range TJ from – 25 °C to 125 °C. Typical values represent the median values, which are
related to 25°C. If not otherwise stated, a supply voltage of VCC = 17 V is assumed.
