Their benefits are such that it’s become surprisingly rare to see a traditional linear power supply with a mains-frequency transformer and rectifier circuit, so [ElectroBoy]’s dual voltage PSU ...

So what’s so exciting about this single-voltage linear power supply? Honestly, nothing — until you start looking at its thermally compensated current limiting circuit. This one is by ...

In needs an external n-channel power mosfet, and can implement buck, boost, buck-boost or SEPIC (single-ended primary-inductance converter, pictured) topologies. Operation is from 4.7 to 85V, covering ...

There are really two kinds of power supplies: Linear and switch-mode. Linear power supplies are your more traditional bricks that musicians have been using for decades, while switch-mode are newer ...
