Part Number: TPS54560B Other Parts Discussed in Thread: TPS54560 , TPS54360 I'm working on a circuit using TPS54560 generating a 15V 2.6A output. The output voltage is around 15V and the chip is working, but there is a huge output ripple (the fluctuation…
Hi Nisha,
Thanks for your patience. TPS54561 is a non-synchronous converter with an internal HS MOSFET and an external LS catch diode.
The quickstart calculator attached should help you get a better idea if this IC is right for your design and give you…
Hi Ignacio,
I accidentally gave you the wrong excel calculator, but looking at your schematic I was able to fill out this new excel calculator with recommended values.
The main changes I would make to your schematic are shown below. Currently I have it…

Hi Please can you help with attached design tool. The problem I am having with the calculator is how it derives the min power…
Hi Tommy,
While I take a look at the schematic, please fill out the quick start calculator attached.
Thanks,

Hi Amrit
1. Could you help modify the current limit range in the calculator?
2. Can the soft start look like a red circle?
3. Could you help check the below schematic and any need to adjust

Hi Henry,
Attached is the parameters that I have input, please check it.
For this measurement I set the PSU at 12 V to the Power simulation board, then the power simulation board was connected to the DUT (test board).
actually the frequency is normal when…
Morning Mike, I'm using the RGT model (see below)

HI Daniel,
Apologies for delay.
1. Please verify using this latest calc.

Hi Akil,
Looks like calc was not updated with correct FET SOA data and RDSON . I have updated it. You will need 2 FETs.
