Your Electronics Open Source

Born around the year 2000 they already are at the second or the third generation and still represent the highest efficiency.

The miniaturization of the systems is a trend followed in all the electronics systems and particularly in the portables ones. In many of them the dimension and the weight of the power supplies are a dominant parameter of the whole system and more and more switching power supplies manufacturers (SMPS – switching mode power supply) define the road-map to increase the density power of their devices

The most common problems to follow the goal focus on two aspects:
The reduction of the passives components dimension (increasing the switching frequency) and reduction of losses (and the corresponding effort needed for the cooling through dissipates and / or ventilators).
