Hi all
I want to design a multiple o/p buck converter
3.3v at 2A
5V at 500ma
1.9 v at 1A
1.2 v at 1.5 A
2.5v at 1 A
i gone through various companies ic's
in most of the ic's to generate voltage less than 5 v it requires max of 7V
My input supply voltage is 12v
I thought of using 12 to 5 v converter module from TI at 6A as a primary step down stage .
i have a doubt that if i put a switched regulator on the o/p of the 5 v regulator module it will create any problem or not as the module itself is switching type
And iam confused in selecting other regulators, as there are many single and dual regulators from various vendors.
And about the switching frequency good to use higher or lower frequency switching ic’s
Important - I need this for a DSP and FPGA power.
Please give suggestions :idea: .
