Power supply for HiperPFS
Posted by: thrmack

How can I create a power supply for HiperPFS (VCC) ? Is it ok to use the LinkSwitch-TN in buck mode, from the input, for this power supply design?
Regards,

Only isolated circuit can be used? I was thinking about the non-isolated buck circuit using LinkSwitch TN2 (https://ac-dc.power.com/products/linkswitch-family/linkswitch-tn2/) to power the VCC of HiperPFS...
sure you can. as far as they both are on primary side.
Ah, I see. So that should be fine, since I´m gonna use a non isolated buck converter (LED driver) at the PFC output, so no transformers in the circuit.

yes you can. as far as the pri and seconary isolation is achieve. PFS Vcc supply is from the bias circuit. PFC Vcc is consider primary.
