Other Parts Discussed in Thread: UC2827-1, UCC3895

Dear TI team

Refer SPRABW0C application note , Please advise what is full bridge control type ( general full bridge or phase-shifted) ?

Is this possible if use controller IC instead MCU control(please suggest feasible part)?

Our team need to design 12Vdc input /380Vdc output ( Power range 500W-1kW)

Based on SPRABW0C suitible for above requirement or not?

Also please advise SPRABW0C magnetic spec for reference (i.e.Transformer turn ration Np,Ns Lp Lo)

Can we use UC2827-1 for full bridge topology(voltage or current fed)?

Best regards

Hi

The SPRABW0C apps note is from our C2000 team, let me try and get one of their apps engineers to respond to your question on the apps note and magnetic spec.

The UC2871-1 can be used in a full bridge or you could use the UCC3895 phase shift full bridge controller. TI does not have any reference designs close to your application but the UCC3895 does have web orderable EVM.

Regards

Peter

Hi Peter

UCC3895 is possible for low input voltage 12v and high output voltage 380V application correct?
Please advise
