Working Principle

The working principle of TE20A0702F01 is toconvert AC to DC. When AC main power is applied,the primary winding of the internal transformer in thepower supply converts AC power to low voltage DCpower. The DC secondary winding consists of aswitched mode power supply (SMPS) circuit, whichregulates the output power to a fixed DC voltage.

The main components in the SMPS are the switchingtransistor, voltage boosting inductor, diode,resistor, capacitor, etc. The switching transistor,inductor and diode form a basic circuit called thehenry loop, which is responsible for controlling theoutput voltage of the AC/DC desktop wall adapter. Whena resistor is connected in parallel to the henry loop,the resistor executes the variable control of theoutput voltage of the power adapter.

The SMPS circuit of the TE20A0702F01 is highlyefficient. The conversion efficiency of the poweradapter is up to 94%, and the efficiency is 95% atthe rated input power and output load. Overvoltage,overcurrent and overload protection increases thesafety of the device.

Conclusion

TE20A0702F01 is a versatile AC/DC desktop walladapter that can be used in a variety of applications.Its working principle is to convert AC power to lowvoltage DC power using a SMPS circuit, which providesa high conversion efficiency, reliable operation andprotection from overvoltage and overload. Withmultiple output numbers of both 3.3V and 5V, it is avery efficient and reliable power adapter for poweringcomputers, office equipment, consumer products,portable electronic devices and LEDs.
