Part Number: PMP23431 Tool/software: Hi sir
Hi sir as shown in PMP23431 reference design I want to design similar power supply using UCC28730QDRQ1 IC. The power supply will have 2 outputs 5V 1A, 5V 200 mA. Can you suggest suitable transformer for…
Part Number: PMP23431 Tool/software: Hi Ti Team,
I am planning to use TI IC for 3 phase to Isolated DC of 12V,10A,auxiliary power supply application. It should work in 3 phase as well as 1 phase
Kindly suggest IC or topology to implement this with…
Hi Francis,
Exceeding the absolute maximum voltage rating will likely damage the device. Normally this would look like a short. PMP23431 has an example of how to support higher voltage buses with an external startup circuit.
I hope this answers your…
Ponkamali,
You can have lower start up current with longer start up time. Please check the PMP23431 test report. It has the startup waveform at 60V input. It took 11seconds though.
Best,
Ning
In that case, why not just use UCC28730? 28730 is a PSR controller and 28740 is a SSR controller.
Please see the ref design using 28730 for this wide Vin range: https://www.ti.com/tool/PMP23431
