I am designing 12W SMPS using NCP1014AP06.
Input- 230VAC ± 15%, 50 Hz
Peak Input current through primary - 410 mA
Primary turns - 418
Primary inductance - 9.55 mH
Secondary turns - 38
Output - 24 V, 0.5 A
PWM frequency - 65 KHz
Duty cycle - 67%
Core selected - EE 19/8/5 (for small size)
Which wire size should I use??
Should I STRICTLY follow the wire size data as per https://www.powerstream.com/Wire_Size.htm ???
According to this data the wire size for primary is AWG 25 & for secondary is AWG 24. If these wire sizes are chosen I need to use bigger core. I have size limitation for the core.
The application note of Fairchild indicates the core size & power requirements. The app. note is attached with other documents.
Can there be any compromise with core size & wire size?????????????????
Please, Help...
