Part Number: TPS40345 Tool/software: Hi,
We are struggling to make a new converter design work using the TPS40345. The issue is that the converter does not start up at power-up. After many tests, we succeeded by first shorting the EN/SS signal to GND…

Hello,
In my design , I use the TPS40345DRCR to output power on a rail. I need to adjust (lower) VREF at times to adjust the output set point:

Part Number: TPS40345 Other Parts Discussed in Thread: LM10011 , LM10010 Hi,
I would like to use a TPS40345 buck controller to deliver between 1.12V (5W) and 1.5V (9W) to a 0.6 ohm load.
The buck's high side is connected to a 3.7V battery, the TPS…
Part Number: TPS40345 Hello,
My customer is using the TPS40345 as FPGA core power supply.
Below is the output ripple capture image. The measured output ripple characteristic is significantly worse than guided by the datasheet.
Below are the customer…
Part Number: TPS40345 Hi
I would like to use the TPS40345 in a new design ,
the new design is a high power LED driver 7V@10A and 4.5V@10A
I plan to test this design using the TPS40345EVM-353 with some modification to the feedback resistor
Can…
Part Number: TPS40345 I want to simulate ripple caused by load fluctuation.
I want to do a simulation that changes the load like 5V/5A -> 5V/8A -> 5V/5A
(Image USB type c load)

Part Number: TPS40345 Good afternoon,
I made a power supply with TPS40345 using webench designer.
The features are:
Vin = 3,3V;
Vout = 0,85V;
Iout = 12A.
I assembled the firsts ten machine and two of these have the power supply that doesn…
