Part Number: TPS54531 Dear TI Teams,
We found an issue with the output voltage is lower than the design voltage when using TPS54531 in our new project. The input voltage is 4.3V and the design output is 3.8V, with a maximum load of 2A. The design voltage…
Part Number: TPS54531 Hi there,
I want to calculate the input current of the device TPS54531 for the Input voltage 6.1V, output voltage is3.3V, since the efficiency is not clear, please let me know how to calculate it?
Part Number: TPS54531 Hi team,
My customer would like to enable IC when the input voltage gets higher than 12V. The input voltage is supposed to be 24V. In this case, Is it possible to use ren1 resistor and ren2 to set the threashold voltage of IC startup…

Hi, We are using the TPS54531DDA for generating a 5V with current requirement of 2.7A (at max load) from 12V to 19V input voltage. at high load condition, we are able to hear the switching noise from this regulator section. we are not…
Part Number: TPS54531 Hi Team,
When the VIN pin has a voltage input, the output is no-load, Float the EN pin to measure the voltage value, will measure 5 volts, Is this phenomenon normal?
Part Number: TPS54531 Hi,
For TPS54531 PCN : 20230217003.1,
May I know it have any date code information can clarify chip is before or after PCN?
Thanks!
Jeff
Part Number: TPS54531 Hi team,
Design with reference circuitry. The input is fixed at 24 V, the output is 7 V, the EN pin voltage is 5.5 V, and the load current is between 100 and 200 mA. There is now a probability (about one-thousandth) that the output…
Part Number: TPS54531 Hi,
For TPS54531DDAR new PCN add TI Mexico as an additional Assembly.
Is it have any marking change or how to define it before PCN or after PCN?
Thanks!

Part Number: TPS54531 Hello,
We are having sporadic startup issues with a design that implements a TPS54531, this design takes 5V to 3.3V with an average load of ~2A.
