UC3865QG3 Overview
20-LCC (J-Lead) is the package in which the ac to dc converter is embedded.There is a AC/DC power converter of Tube available.In this case, the AC/DC converter is mounted in the way of Surface Mount .Ideally, the ac dc converter should be operated at a temperature of 0°C~70°C TA degrees Celsius.Analog IC type SWITCHING CONTROLLER is utilized in this AC DC converter.When the switching frequency reaches 10kHz~1MHz , the circuit is closed.The AC/DC converter is capable of being used when the supply voltage is 10.5V~22V (Vcc/Vdd).In total, it has 20 terminations.There are 20 pins on the ac/dc converter.There are a total of 20 pins on the ac-dc converter.You can search similar acdc converters based on UC3865 family.There are 2 outputs to be processed.There are a ac to dc conversions included in Switching Regulator or Controllers .We have set the output current to 200mA .As a result, its output voltage is 1.7V .As long as AC to DC converter is operated at frequency 450kHz ,it is capable of attaining high efficiency.
