BA (extended Blanking & Auto-restart enable)
The BA pin combines the functions of extendable blanking time for over load protection and
the external auto-restart enable. The extendable blanking time function is to extend the
built-in 20 ms blanking time by adding an external capacitor at BA pin to ground. The
external auto-restart enable function is an external access to stop the gate switching and
force the IC enter auto-restart mode. It is triggered by pulling down the BA pin to less than
0.33 V.
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. The FB-
Signal is the only control signal in case of light load at the Active Burst Mode.
CS (Current Sense)
The Current Sense pin senses the voltage developed on the series resistor inserted in the
source of the integrated CoolMOS
TM
If voltage in CS pin 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 650 V

integrated CoolMOS™)
Drain pins are connected to the Drain of integrated CoolMOS™.
VCC (Power supply)
VCC pin is the positive supply of the IC. The operating range is between V

Introduction
ICE3RBR0665JG (ICE3RBRxx65JG series) is the new member of ICE3RBRxx65Jx in DSO-12 package. A high
voltage Startup Cell is integrated into the IC which is switched off once the Undervoltage Lockout on-threshold
of 18 V is exceeded. This Startup Cell is part of the integrated CoolMOS
TM
. The external startup resistor is no
longer necessary as this Startup Cell is connected to the Drain. Power losses are therefore reduced. This
increases the efficiency under light load conditions drastically.
The particular features are the active burst mode, propagation delay compensation, modulated gate driving,
auto-restart protection for Vcc overvoltage, over temperature, over load, open loop, built-in soft start, blanking
window and frequency jitter. It provides the flexibility to increase the blanking window by simply addition of a
capacitor in BA pin. In order to further increase the flexibility of the protection feature, an external auto-restart
enable feature is added.
The intelligent Active Burst Mode can effectively obtain the lowest Standby Power at light load and no load
conditions. After entering the burst mode, there is still a full control of the power conversion to the output
through the optocoupler, that is used for the normal PWM control. The response on load jumps is optimized
and the voltage ripple on Vout is minimized. The Vout is on well controlled in this mode.
The usually external connected RC-filter in the feedback line after the optocoupler is integrated in the IC to
reduce the external part count.
Adopting the BiCMOS technology, it can increase the design flexibility as the Vcc voltage range is increased to
25 V.
It has a built-in 20 ms soft start function.
There are 2 modes of blanking time for high load jumps; the basic mode and the extendable mode. The
blanking time for the basic mode is set at 20 ms while the extendable mode will increase the blanking time by
adding an external capacitor at the BA pin in addition to the basic mode blanking time. During this blanking
time window the system can give the maximum power to the loading.
In order to increase the robustness and safety of the system, the IC provides Auto Restart protection. The Auto
Restart Mode reduces the average power conversion to a minimum level under unsafe operating conditions.
This is necessary for a prolonged fault condition which could otherwise lead to a destruction of the SMPS over
time. Once the malfunction is removed, normal operation is automatically retained after the next Start Up
Phase. To make the protection more flexible, an external auto-restart enable pin is provided. When the pin is
triggered, the switching pulse at gate will stop and the IC enters the auto-restart mode after the pre-defined
spike blanking time.
The internal precise peak current control reduces the costs for the transformer and the secondary diode. The
influence of the change in the input voltage on the maximum power limitation can be avoided together with
the integrated Propagation Delay Compensation. Therefore the maximum power is nearly independent on the
input voltage, which is required for wide range SMPS. Thus there is no need for the over-sizing of the SMPS, e.g.
the transformer and the output diode.
Furthermore, it implements the frequency jitter mode to the switching clock such that the EMI noise will be
effectively reduced.
