Planar Transformer-----Universal input 50W 12V
¡ïIntroduction
Switching mode power supplies started on the 60´s and they were developed mainly for aero***ce and militar applications due to the big difference in terms of weight and volume with regards to the linear ones. Actually there are many proposal to improve the performance, efficiency and the size of these power supplies, which are used either in industrial and telecom applications. In this application note we intend to show the design of a switching mode power supply low output power with topology Forward Dual, small size and very high efficiency. The working frequency is high and the usage of planar transformer technology.
¡ïCharacteristics and main advantages of this power supply are as follows:
&©|8226; Low output power (50W).
&©|8226; Low bill of materials price.
&©|8226; High efficiency (80-95%).
&©|8226; Built with a current switch.
&©|8226; Protection against overload.
&©|8226; Very good efficiency with low loads.
&©|8226; Switching frequency 300KHz approx.
&©|8226; Easy and robust design.
&©|8226; Small size and light weight.
¡ïPlanar transformers advantages
Usage of planar transformers is a very attractive solution to improve our switching mode power supplies. These devices furthermore than having a co***ct and smaller size than any other transformer, we get many other advantages. The market is getting more and more competitive and by this there are a lot of improvements in the power switching electronics, by the way there is a continuous research in these kind of components. The main advantages of the PREMO,S.A. planar transformer range might be summarized as follows:
&©|8226; Less height.
&©|8226; Less weight.
&©|8226; Reduced dimensions.
&©|8226; Very low stray inductance.
&©|8226; Low winding capacitances.
&©|8226; Less losses.
&©|8226; Excellent repeteability.
&©|8226; Improved thermal performance.
&©|8226; More reliability.
&©|8226; High output power handling with smaller dimensions.
&©|8226; Better cooling.
