Part Number: TPS546D24AEVM Other Parts Discussed in Thread: TPS546D24A 1. I think the schematic of the TPS546D24AEVM demo board has a problem. That is Master and Slave Config pin(MSEL2) are connected together.
This will make Master config affected by Slave…
Part Number: TPS546D24AEVM Other Parts Discussed in Thread: TPS546D24A Hey there,
My customer has this 2phase EVM in hand. What it the simplest way to make it single phase? Then, they will evaluate it with Fusion.
Thanks.
Part Number: TPS546D24AEVM Hi there,
Could you kindly explain the test conditions as the attachment below? As far as I understand about the buck, input current is the sum of output current and IC-operating current, in that, input current is similar…
Part Number: TPS546D24AEVM Other Parts Discussed in Thread: TPS546D24A , TPS546D24 Hi there,
Does TPS546D24AEVM board could output a voltage higher than 1.5V? The inductor value on EVM board is 150nH, Does the Output support 0.6 V to 5.5 V at 80 A?
When…
Part Number: TPS546D24AEVM Other Parts Discussed in Thread: TPS546D24A , I am using the TPS546D24AVEM and I am wondering how to control the output current? I have a 5V power supply connected to Vin and Ground In and then a programmable load. I know that…
Hi Timothy,
Is there a reason you want to use TPS546D24 instead of TPS546D24A? Because TPS546D24A is a newer version and we generally recommend it for new designs.

For an estimate of the efficiency at a specific operating point, I would recommend using WeBench and matching the design components selection, then using it's efficiency estimator. This is important since efficiency is affected by external component…
Santhana Krishnan T L said: 1. I would like to calculate the power dissipation of this device. Is there any tool/excel available to calculate the Power dissipation of this device? I see some of the information not available to calculate the MOSFET losses…
Did some extra testing.
I’ve changed inductors from 1uH to 150nH that I borrowed from TPS546D24AEVM-2PH. Added 2x1000uF bulk capacitors on 1V2 output as well as 2x1000uF on the 12V input rail. The result is exactly the same. The converter ramps up the…
Hi JH,
Please check out the TPS546D24A-2PH EVM: https://www.ti.com/tool/TPS546D24AEVM
This is a good place to start the design from. You can also generate a design on WEBENCH.
I also recommend you fill out the design calculator to determine key components…
