Circuit Schematic 12V/280mA Transforerless Power Supply using LNK340 IC

Power Supply. - This is electronic Circuit Schematic 12V/280mA Transforerless Power Supply using LNK340 IC like in Figure 1 below. In this circuit schematic the basic component used is LNK340 IC. 

In here we will give you global description about Circuit Schematic 12V/280mA Transforerless Power Supply using LNK340 IC and then we will give you link to continue your reading from original source as external website.

Description

Circuit schematic like in Figure 1 above is Circuit Schematic 12V/280mA Transforerless Power Supply using LNK340 IC. ElectronicKitSchool site describe that this is one of the transformerless power supply circuit for you who want to build yourself this transformer power supply. This transformerless power supply here mean that we not using transformer step down to low the 220VAC to 12V or other. But in here we will use special component to do this work easily.

The circuit diagram of a practical 12V/120mA transformerless switch mode power supply is shown above. Resistor R1, capacitors C1 and C2, diodes D1 and D2 and inductor L1 forms the input stage. D1 and D2 forms the rectifier section while C1 and C2 are input filters. Resistor R1 which is a fusible resistor limits the inrush current, increases differential mode noise attenuation and also serves as an input safety fuse.

And now you can read more you knowledge about Circuit Schematic 12V/280mA Transforerless Power Supply using LNK340 IC from the original source article using link [here].
