TPS7A78: 12V AC to 12V DC converter for power supply

Part Number: TPS7A78

Hi Team,

Our customer is Looking for AC to DC converter for power supply with the following information:

Input: 12V AC
Output: 12V DC
It's part of a basic transformer, rectifier, regulator power supply.
This will need to support higher current though, around 2.5 amps

The customer is trying to get to flat line at 12V DC. Assuming they have passed through a 12:1 transformer and rectifier.

They will be using a full rectifier so the input into the regulator will be the full wave or wave form B on the bottom (Please see image below). Just need to take out the ripples with the regulator.

Do we have an IC to offer on this? 



  • Hi Jonathan, 

    This is an interesting application but we don't currently have an AC-DC solution from the LDO product line that can support 2.5A of current. I am reaching out to our other team members to see if we have anything in the roadmap that could potentially work for this kind of application. 

    Do you know what is the solution your customer currently have for this type of application?
