Part Number: PMP10834 Other Parts Discussed in Thread: PMP10833 , PMP20122 Hi,
I'm thinking about using the same circuit as the one presented in your board PMP10834 for my design that needs an AC/DC with 5V output (max 0.5A).
To save space and costs…
Part Number: PMP20122 Other Parts Discussed in Thread: UCC28710 , PMP10834 Hello,
Can I get the design calculation details for PMP20122 to modify it to my requirement. I have DC input range 110V - 200V and I wanted to have 12V/ 200mA output design.…
Hi Pan,
Yes, you can use UCC28C42D for a HV buck. Another example is PMP10834:

Also, to reduce switching losses, we generally design the converter to be operated at DCM. Therefore, the duty cycle at maximum input will be…
Part Number: UCC28C45 Other Parts Discussed in Thread: PMP10834 Dear TI EE:
I want to use UCC28C45D for Fly-Buck Converter.
I want to take'TI PMP10834.1 SCH' as reference.
The SCH from PMP10834.1 as below picture.
I want to refer this SCH to meet…
Check out the following reference design. It is cited as a fly-buck, but it's really a buck with an extra winding to bias the controller, which is pretty much what you will need.

You don't need the optocoupler circuitry shown…
To clarify Masumi, the UCC28911 can give more output power in non-isolated flyback configuration than the UCC28881 can deliver as a non-isolated buck.
In non-isolated buck mode, the UCC28911 delivers less power than it does in flyback mode, and if…
Hey Bob,
We do have products that can meet your non-isolated converter needs.
The UCC28700 is a primary side regulator that can be used as a non-isolated buck converter as shown in this reference design: http://www.ti.com/tool/PMP10937
If cost…
