DESCRIPTION
VIPer100™/100A, made using VIPower M0
Technology, combines on the same silicon chip a
state-of-the-art PWM circuit together with an
optimized, high voltage, Vertical Power MOSFET
(620V or 700V / 3A).
Typical applications cover offline power supplies
with a secondary power capability of 50 W in wide
range condition and 100W in single range or with
doubler configuration. It is compatible from both
primary or secondary regulation loop despite
using around 50% less components when
compared with a discrete solution. Burst mode
operation is an additional feature of this device,
offering the ability to operate in stand-by mode
without extra components.

Pins Functional Description
Drain Pin (Integrated Power MOSFET Drain):
Integrated Power MOSFET drain pin. It provides internal bias current during start-up via an integrated
high voltage current source which is switched off during normal operation. The device is able to handle
an unclamped current during its normal operation, assuring sel f protection aga inst voltage s urges, PCB
stray inductance, and allowing a snubberless operation for low output power.
Suorce Pin:
Power MOSFET source pin. Primary side circuit common ground connection.
VDD Pin (Power Supply):
This pin provides two functions :
■ It corresponds to the low voltage supply of the control part of the circuit. If V
up current source is activated and the output power MOSFET is switched off until the V
reaches 11V. During this phase, the internal current consumption is reduced, the V
a current of about 2mA and the COMP pin is shorted to ground. After that, the current source is shut
down, and the device tries to start up by switching again.
■ This pin is also connected to the error amplifier, in order to allow primary as well as secondary
regulation configurations. In case of primary regulation, an internal 13V trimmed reference voltage is
used to maintain V
on V
pin by transformer design, in order to stuck the output of the transconductance amplifier to the
DD
at 13V. For secondary regulation, a voltage between 8.5V and 12.5V will be put
DD
high state. The COMP pin behaves as a constant current source, and can easily be connected to the
output of an optocoupler. Note that any overvoltage due to regulation loop failure is still detected by the
error amplifier through the V
voltage, which cannot overpass 13V. The output voltage will be

somewhat higher than the nominal one, but still under control.

DD
Compensation Pin
This pin provides two functions :
■ It is the output of the error transconductance amplifier, and allows for the connection of a compensation
network to provide the desired transfer function of the regulation loop. Its bandwidth can be easily
adjusted to the needed value with usual components value. As stated above, second ary regulation
configurations are also implemented through the COMP pin.
■ When the COMP voltage is going below 0.5V, the shut-down of the circuit occurs, with a zero duty cycle
for the power MOSFET. This feature can be used to switch off the converter, and is automatically
activated by the regulation loop (no matter what the configuration is) to provide a burst mode operation
in case of negligible output power or open load condition.
OSC Pin (Oscillator Frequency):
An Rt-Ct network must be connected on that to define the switching frequency. Note that despite the
connection of R
provides also a synchronisation capabilit y, when connected to an external frequency source.
to VDD, no significant frequency change occurs for VDD varying from 8V to 15V. It
