Part Number: TPS543C20A Other Parts Discussed in Thread: TPS548D21 I tried to perform Load transient of any combination. Unable to get the proper waveform. Output voltage goes negative. Looks like webench model is not working. Other IC like TPS548D21…
Hello,
can you please if any of these will fit your requirements? These are our high current converters:
TPS546D24A
TPS543C20A
TPS549D22
TPS548D21
TPS548D22 -
Thanks

Hi Manish,
My expertise is on devices under 10A, the device you were initially testing TPS54623 has Iout (max) = 6A. Per your specifications, it looks like you are looking at a higher current rating (+21A) device. From some initial search it looks like…
Hi Nick,
Leaving the 1000pF cap on pin 37 of the TPS548D21 is OK if using the part in place of the TPS548D22. I would be sure to make sure the connection to ground is direct and the routing from pin 37 to C270 is routed away from noisy lines on the board…
Hi ,
You can refer below PN#.
1. TPS546D24A - 2.95-V to 16-V, stackable 40-A synchronous SWIFT buck converter with pin-strapping and PMBus
2. TPS543C20A - 4-V to 16-V, 40-A synchronous SWIFT buck converter with adaptive internal compensation
3. TPS548D22 - 1…
Hi D. Tourres,
The tracking function for the TPS548D22 is disabled and cannot be enable by the mode pin setting. Since this function is disabled, the RSV_TRK (reserve for tracking) is already pulled down to ground by it's internal circuitry.
The…
Hi Pengyu,
TPS548D21 and TPS548D22 are almost the same. The only difference is pin 37. For TPS548D21 it is REFIN_TRK that can be used to override the internal reference for tracking purposes. For TPS54*D22, it is not intended for external connection. …
Vidhya,
TPS543C20 is a 40 A device with the same package and similar but not identical pin out. Also it does not have PMBus.
TPS548D22 is also a 40 A part with the same package, similar but not identical pin out and slightly different function without…
