Every day, designers are challenged to come up with solutions that make the user-experience better, save energy, take up less space and use fewer components – not to mention cost less and are easy to make. Oh, and throw into the mix getting it done fast so they can beat the competition to market.[......]
Reverse Polarity: What Causes It And What You Can Do About It (Part 2 of 4 on Reverse Polarity Protection)
Nobody wants their system to fail or, worse yet, burst into flames. But that’s what can happen if reverse polarity is allowed to do its damage.
Reverse polarity is the result of steady-state reverse bias or a negative transient. It’s a dangerous electrical condition that can be difficult to preve[......]
Introducing Fairchild’s Online Design Tools: Part 6: Input Voltage Analysis and Input Capacitance Calculation for Single-ended Flyback Converter
The input voltage and the input capacitance can influence performance in a flyback converter. Let’s look at how to analyze the input voltage and calculate the input capacitance.
When a flyback controller is operating in steady state, the rectified AC input voltage (through DIN1 to DIN4) provides[......]
