Recommendation for 24VDC, 12A output

AC-DC Power Converters
1

Hi, below are my requirements

Input = 90 to 265 VAC,

Output = 24VDC, 12A, isolated output.

can HR1211 (PFC+LLC) be used by changing the T1 push-pull transformer as in EVHR1211-Y-01A.

Alternate IC or any recommendation please let me know.

Thanks,

Lokeshwar

Hello,

Yes, you should absolutely be able to use the HR1211 where changing T1 in this design should adjust the output. I would also adjust the capacitor ratings of the secondary side of the circuit such that all components here should be able to handle the 24Vdc output voltage. As a general rule, all components should be sized to 2-3x the voltage to account for any thermal derating.
