... Current Mode Topology: The current mode control method, like the one integrated in the VIPer100A-E/ASP-E, 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 current ...

... The equivalent switching frequency is also lower than the normal one, leading to a reduced consumption on the input main supply lines. This mode of operation allows the VIPer100A-E/ ASP-E to meet the new German "Blue Angel" Norm with less than 1W total power consumption for the system when working in stand-by mode ...
