If you need a higher input voltage range, you can try TPS54540 or TPS54340. If you suspect fluctuation on your 24V bus, you may want to add some additional filtering.
Flora-san,
Thank you for your response. We would like to get the information as soon as possible because our customer must select device.
We would like to know if there is any difference which relates to efficiency between internal of TPS54340/60…
voltage like 12V,15V,18V,24V & tps5450/5430 is suitable for 5V&3.3V supply. Negative voltage -12V is generate by using Tps54540 its ok or not? . Today i have install the switch pro simulation software . i have simulate 12v,15V,18V,24V voltage, when we…
Hello Dhimat,
We do not have any dual switchers with integrated fets rated to 40V.
Our dual integrated fet switchers, like TPS55386, are only good to 28V.
For single switcher with integrated fets see:
TPS54540 TPS54040A TPS54140A TPS54240 TPS54340…
Ajesh,
If you need to go down to 1.2V, you may want to consider a Step down controller such as the LM25085A or if you are looking for something with an integrated switch, then I would suggest looking at the TPS54540 or other similar devices in this…
Hi Murray, Thank you very much for your quick response. I very much like the proposed chip. We will evaluate purchasing the EVM. Surely addition to the GSM modem I must also supply a XBee modem. I need to provide in this instance up to 5A peak. Can you…
Anything from my group would be non-synchronous solution such as TPS54240 for 2A, TPS54340 for 3A and TPS54540 for up to 5A output. I'm sure there are other possibilities from other groups. If you like LMZ31707, I'm sure you could pre-regulate down to…
Part Number: TPS54260 Tool/software: Dear sir,
Recently Delta reported that some TPS54260DGQR (the left) can work well, but some IC not (the right) which is from TI sample stock, Label as following.
Delta's schematic as following:
Inverting…
Hi Iven,
At present we do not have a PSpice model for TPS54521. However, we have PSpice models for several other devices similar to this part
TPS54620: 6A Current Mode Similar Vin
TPS54540: 5A Current Mode Higher Vin
TPS54525: 5A DCAP2 Similar…
