Hello there,
We have used the reference design PMP10397 as it is except the transformer is changed to below specs.
Vin min=300V DC
Vin max=650 DC
Vout 15V / 0…
Hi Dirkie,
thanks for your interest in TI. A flyback would work well for this use case. Take a look at PMP10397. It is fairly similar to your design requirements: www.ti.com/.../PMP10397

Hi Mathis,
UCC28700 PSR flyback controller has a minimum on time requirement due to leading edge blanking time. UCC28700 buck from 1000V to 24V is not doable.
Alternatively, I think a better option is to use a BJT Flyback like PMP10397. You can design…
TI reference design PMP10415 is a 4 channel 54W 300VDC to 528Vac power supply.
It doesn't exactly meet your needs but it can be used as starting point for your design.
Also PMP10397 is a single output 85Vac to 528Vac based on a BJT switch that you…
The UCC28740 is more suitable for your application since the opto feedback is more suitable for a multi output flyback topology.
PSR type controllers rely on the shape of the auxiliary voltage waveform to determine when the secondary has ceased to conduct…
Hi,
Something like the design in the link below but with the secondary truns increased to give the higher output voltage, www.ti.com/.../PMP10397.1 ;tisearch=tidesigns&keyMatch=UCC28722&tisearch=Search-EN-Everything
