Original question:

UCC28951: Realization of ACDC converter

UCC28180: Realization of ACDC converter

Part Number: UCC28180
Other Parts Discussed in Thread: UCC28070,

Hi support team,
I am looking for a 2-output ACDC converter with the following specifications.

ACDC converter specifications
・AC Input Voltage Range: 85 to 264V
・DC Output 1: 60V, 10A
・DC Output 2: 12V, 30A
・Isolated : Yes
・Application: Large capacity charger

In the related question, UCC28070 was introduced as a pre-regulator that generates DC390V.
However, I am considering UCC28180 because I want to use a simple device.
We plan to generate DC390V with UCC28180 and place two UCC25640x systems in the latter stage.

Is UCC28180 suitable for this application?

Please let me know if there is another suitable IC.

Regards,
Dice-K

    Hello Dice-K,


    From the info you've provided, you should be able to use the UCC28180 with two UCC25640x to power your application. Keep in mind that with your ~1kW application, the boost inductor will be larger and the output caps will need to handle higher ripple by using the UCC28180 than would be the case if you used the interleaved output of the UCC28070.
