ISOLATED SWITCHING POWER SUPPLY
Posted by: telles_cps

Hi guys, I´m new in projects with Switching Power Supplies. I was read the EPR32.pdf and I find a decive to assembly.
This project contais a output with -24v/50mA
How I can swap the voltage to positive and impruve the Iout to 1A?
Thanks to all!!

Hi, PI-csbabu!
I need multiples outputs. My ideia its made a power supply with 3v3, 5v and 24v (CC), each with 300mA.
Input 110-220 AC.
TKS!
Hi,
I recommend to you latest INNOSwitch series to reduce number of components instead of TOPswitch. In terms of design, use additional 6T stack winding on W5 &W6 to get +24V. Since 24V output delivering more power, close feedback loop on that. Remove w7 and w8. Please use PIexpert tool available online for preliminary design analysis.
Hi,
Welcome to power supply design. Do you need single output or multi output ? The application note has multiple outputs and total output power is around 25W peak. Please let me know the design requirements like input voltage range, total power & output voltage, so that I can suggest you best suitable part.
