A super quiet EP13 size flyback transformer. Primary inductance is 4.31mH +/- 10%. Switching frequency is 60 KHz minimum. The input is rated at 120V. There are 2 outputs rated at 2.5V/600mA and an aux rated at 17V/20mA. The power rating is 3.4VA, but it could handle twice that at 6.8VA. The design reduces electrical…

### Switched Mode Power Supplies

A switched mode power supply (SMPS) is a more modern and efficient take on the older power supplies known as linear supplies. LINEAR SUPPLIES Linear supplies would often take in line voltage, transform this via a low frequency silicon steel core transformer to a lower voltage. Then through rectification using diodes, and filtering using capacitors,…
