About application to DC to DC boost converter

Part Number: UCC28C43-Q1

Hi,

Customer wants to make Boost converter using UCC28C43-Q1.

・Vin=DC120V to 380V
・Vout=400V (Iout=not fix)

Can UCCx8C4x series be used for 400V output Boost converter?
And Do you have Boost converter design example?
Or Can you recommend to other device?



Best Regards,
Yusuke/Japan Disty




  • Hello Yusuke-san,
    Yes the UCC28C43-Q1 can be used as a boost converter in this application.
    The diagram labelled " Typical Automotive Application Example" on page 1 of the datasheet shows how to start up the device from a high voltage input.
    I checked and I could not find any reference design with a high voltage input but once you know the power rating of your product it will be relatively straightforward to design this product.
    Regards
