RE: Does TI have a P2P solution like to Si8273BB-IS1?

Hello Muhammet,

Unfortunately we can't reveal this information over E2E, as its protected by NDA. E2E is intended for technical questions about our devices, so if you have a question regarding datasheets specs or applications, I am happy to help.

However if you are still interested in the answer to this question we would need your business sales representative or assign an FAE from TI to make sure all of the NDAs are in place, and then we would be able to have a conversation about this question offline.

Hi, Muhammet,

You should check out UCC21521. It has a DT pin which can be tied to VCCI to disable the internal dead-time functionality.

Let us know if you have further questions.

Best regards,

UCC20520DWR has a single PWM input.

This is correct. Do you need a single PWM input or dual. 

UCC21521 would be closest match to SI8273, which is what Don said. one of the "NC" pins on UCC28730 would jus tneed to be tied to VCC..... Thats it.

Muhammet,

UCC20520 and UCC20225 are essentially the only "functionally equivalent" devices, with single-input (PWM pin, rather than INA/INB).

However, these devices are not Pin2pin as the package is different.

UCC20225 also has lower isolation ratings due to smaller package which may make it unsuitable for you.

If you are open to using a part with dual-inputs (INA+INB), you have  many more options which you can substitute and will be nearly P2P, and same footprint.
