UCC28C44: 36V or 48V Input PSR Device

CHEN YAN

Part Number: UCC28C44
Other Parts Discussed in Thread: UCC28C43

Hi,

My customer is looking for a 36V or 48V input voltage PWM controller to do a open-loop, fixed frequency, fixed duty cycle, primary control forward circuit, it seems like UCC28C43 and UCC28C44 can do the topology, but the input voltage is a little low. Could you please recommend 36V or 48V input voltage device? Thanks.

Best Regards.

Hello Chen,

I am assuming that they require a controller with a PSR flyback topology capability? Can you please clarify that.

What is the design spec? output power, output voltage, switching frequency?

Regards,

Sonal

Hi Chen,

Since it has been nearly a week since TI has asked for more information we can only assume that you have made some progress on this issue by yourself.

Please open a new post if you have more questions.

Peter
