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.

VIPer100/SP - VIPer100A/ASP Operation Description: Current Mode Topology: The current mode control method, like the one integrated in the VIPer100/100A, uses two control loops - an inner current control loop and an outer loop for voltage control. When the Power MOSFET output transistor is on, the inductor current (primary side of the transformer) is monitored with a SenseFET technique and converted into a voltage V amplified output voltage error) the power switch is switched off ...

They may be classified into two categories: - Minimizing power loops: The switched power current must be carefully analysed and the corresponding paths must be as small an inner loop area as possible. This avoids radiated EMC noises, conducted EMC noises by magnetic coupling, and provides a better efficiency by eliminating parasitic inductances, especially on secondary side ...
