I am working on a project that will boost my Lipo voltage to 5V. I am looking at trying to use a boost converter like the TPS61235P from TI. Is there a good way to prototype this IC package (9-VFQFN) without having to create a custom breakout board just for this IC?

  • \$\begingroup\$ Getting a PCB made is so cheap and convenient nowadays I gave up prototyping. I just design a circuit with a chip in it and get it made. If it doesn't work I fix it and get a new version made. Chips are so small now it's just easier that way. \$\endgroup\$ – Majenko Nov 19 '16 at 23:40

    \$\begingroup\$ Especially parts like that where you have to pay close attention to PCB layout. \$\endgroup\$ – Majenko Nov 19 '16 at 23:42
  • \$\begingroup\$ Alternatively, ready made breakouts of lipo boost converters to 5V are cheap and available. \$\endgroup\$ – Wesley Lee Nov 19 '16 at 23:44
  • \$\begingroup\$ @WesleyLee the reason I was trying to create one myself was because a lot of the 5V Lipo/Li-ion boost converters that I found would limit current at around 1A when they could give potentially 2-2.5A including efficiency. \$\endgroup\$ – Benjamin Owen Nov 19 '16 at 23:46

    \$\begingroup\$ I am just trying to help. Regarding "prototyping", you can't, without making a PCB, and only if you stop "assuming" and follow datasheets and specifications. \$\endgroup\$ – Ale..chenski Nov 20 '16 at 2:36

TI is usually good about listing evaluation modules on the "Tools & software" section of the product page. In this case it has a link to TPS61236EVM-676, available for $49 from TI direct.

Other companies may do something similar; as always examine the appropriate product page.
