DESCRIPTION
VIPer100B/100BSP, made using VIPower M0
Technology, combineson the same silicon chipa
state-of-the-art PWM circuit together with an
optimized high voltage avalanche rugged Vertical
Power MOSFET (400 V/ 6 A). Typical
applications cover off line power supplies with secondary power capabilityof 100Wina US
mains lines configuration.Itis compatible from
both primaryor secondaryregulation loop despite
using around 50% less components when
compared witha discrete solution. Burst mode
operationis an additional featureof this device,
offering the possibility to operate in stand-by
mode without extra components.

PINS FUNCTIONAL DESCRIPTION
DRAIN PIN:
Integrated power MOSFET drain pin.It provides
internal bias current during start-up via an
integrated high voltage current source whichis
switchedoff during normal operation. The device ableto handlean unclamped current duringits
normal operation, assuring self protection against
voltage surges, PCB stray inductance, and
allowinga snubberless operation for low output
power.
SOURCE PIN:
Power MOSFET source pin. Primary side circuit
common ground connection.
VDD PIN:
This pin provides two functions:It correspondsto the low voltage supplyof the
control partof the circuit.If VDD goes below 8V,
the start-up current sourceis activated and the
output power MOSFETis switchedoff until the
VDD voltage reaches 11V. During this phase,
the internal current consumptionis reduced,
the VDD pinis sourcinga currentof about 2mA
and the COMP pinis shortedto ground. After
that, the current sourceis shut down, and the
device triesto startupby switching again. Thispinis also connectedto the error amplifier, orderto allow primaryas wellas secondary
regulation configurations.In caseof primary
regulation, an internal 13V trimmed reference
voltageis usedto maintain VDDat 13V. For
secondary regulation,a voltage between 8.5V
and 12.5V will be put on VDD pin by
transformer design,in orderto stuck the output the transconductance amplifierto the high
state. The COMP pin behaves asa constant
current source, and can easilybe connectedto
the outputof an optocoupler. Note that any
overvoltage dueto regulation loop failureis still
detectedby the error amplifier through the VDD
voltage, which cannot overpass 13V. The
output voltage will be somewhat higher than
the nominalone, but still under control.
COMP PIN:
This pin provides two functions:Itis the outputof the error transconductance
amplifier, and allows for the connectionofa
compensation networkto provide the desired
transfer function of the regulation loop. Its
bandwidth can be easily adjusted to the
needed value with usual componentsvalue. As
stated above, secondary regulation
configurations are also implemented through
the COMP pin. When the COMP voltageis going below 0.5V,
the shut-downof the circuit occurs, witha zero
duty cyclefor the power MOSFET. This feature
canbe usedto switchoff the converter, andis
automatically activated by the regulation loop
(whateveris the configuration)to providea
burst mode operationin case of negligible
output poweror open load condition.
OSC PIN: RT-CT network mustbe connectedon that pin define the switching frequency. Note that
despite the connection of RT to VDD,no
significant frequency change occurs for VDD
varying from 8V to 15V.It provides alsoa
synchronisation capability, when connectedtoan
external frequency source.
