Discussion on Coordination Circuit of PC817 and TL431

TL431 is a precision voltage regulator, and PC817 is a photocoupler. In switching power supplies, the design of the voltage regulator feedback circuit is usually carried out with the cooperation of TL431 and PC817. In the flyback power supply design, the feedback circuit often uses them as a reference. Therefore, the cooperation between the two is always a topic that engineers like to...

S8050 NPN Transistor for Low Signal Applications

The S8050 is an NPN transistor with low voltage and high current that can be used to create Class B push-pull amplifiers. In the bipolar junction transistor S8050, holes are the minor carriers while electrons are the major ones. S8050 is primarily used as an amplifier for boosting low signals, such as audio amplifiers, and has a high DC gain of 300. Before we examine the S8050 datasheet, let's...
