Part Number: TPS61378-Q1
Other Parts Discussed in Thread: TPS61178, TPS61288, TPS55340

Hello, we tested and validate the TPS61378 chip to have +15 / 18 Fdc from the +5Vdc.

But the part TPS61378 is not available from any sealer in Europe.

Is there another similar, symple and new part from Texas to step-up from 5 Vdc to 15/18 Vdc ?

Thank you in advance.

Regards

Paolo

Hello Liu, we tested it or 1 Ampere but for us are necessary only 0.7 Ampere.

In this conditions, 15 Vout and 0.7 Amp. the component TPS61378 works perfectly, it is cold and stable.

I hope to find another chip with similar features in Texas porfolio.

Thank you.

Hello Liu, I checked the TPS61288 but it has quite similar problem, a delivery time very long.

I will be very happy if you will give to me SOME indicationS of a step-up chipS that it ARE easier to find

with similar characteristic of the TPS61378.

Hi Paolo,

I would suggest you contact the TI local Sales & FAE team for help. They could check the part lead time and may contact TI planner team for help.

I am willing to help answer your technical questions but not good at dealing the long delivery time problems.

TPS61378 is our latest device and don't have other pin-to-pin devices. The TPS61288, TPS61178 have different pin map. Another suggestion is TPS55340.
