Part Number: TPS54394
Hello E2E,
Please help to review the design below and kindly share your feedback. Our customer tried implementing the circuit in real life to see if it works, but they don't have the appropriate tools to solder everything at the…
Part Number: TPS54394 Hello Ti,
I am using TPS54394 for 1.8V output, and we found the output vlotage is abnormal and powergood drop.
Please help to clearify.
Thanks!

Part Number: TPS54394 Minimum Vin1 and Vin2 for TPS54394 for output of 1.1V on VOUT1 and 3.3V on VOUT2.
I am designing this regulator with the input range of 4.5V to 16V (USB-C VBUS), and so I need the TPS54394 for output to be 1.1V on VOUT1 (worst case…
Part Number: TPS54394 It's funny on one thread regarding this part, someone said the user's layout was very bad because the switch node was connected to the inductor using a different layer. That is the (poorly) recommended layout on page 16 of the data…
Part Number: TPS54394 The datasheet for this part indicates a VIN range of 4.5 to 18V. The block diagram and text throughout the document show VIN1 feeding an internal 5V regulator. How is it supposed to regulate to 5V if the input is 4.5V?
Hi Noah,
Are you able to open any of the installed test circuits for TI parts? e.g. TPS54394
Search for that, RMB to pull up the options, last one is Open Model Test Circuit
I just did INA317 as it runs very quickly. TPS54394 has a long simulation time…
Part Number: TPS54394 Hello,
I need to run a simulation of the using the TPS54394 to see if I can modify it correctly to power sequence in the correct order for an FPGA. Right now I'm just trying to get the model to run, and I more or less used the design…
Part Number: TPS54394 Hello,
I am working with TPS54394 and we are generating two 5V outputs from 12V input. In channel 1, the output ripple seems ok, however in channel 2 the ripple of 5V output is too high.
In both channels the average output value is 5V…
Part Number: TPS54394 Hi, There
We are using TPS54394 as our power solution:
1.CH1 is 3.3V@1.5A,and Cout is around 100uF;
2 CH2 is 1.0V@2A, and Cout=660uF according to FPGA requirment.
3. Vin=12V ,Vinmax=14V
Per TPS54394's spec, Cout range is 22-68uF…
Part Number: TPS54394 Other Parts Discussed in Thread: TINA-TI , Hi I would like to ask for the TPS54394 transient spice model to be used on the Tina-Ti tool. Thanks in advance.
