What ICs are used in this rocket?

[soldar]

Considering OP's "friend" was apparently illegally selling semiconductors to the commies - and now he's asking what semi's are going into commie rockets?
We're being trolled yet again    I have to conclude he's working for 'em.
....
Now you're asking us again about stuff the commies have? All your "schematics" use Linear Tech parts - the most expensive in the business.
Did you finish your drone-making startup? Hint: china makes all the major components - rare-earth PM motors, cameras, batteries etc.
Plan your next trip to Shenzhen already.

Your repeated use of "commies" sounds rather silly and outdated to me.

Hi,

and finally completely alien parts with no info available

So , appreciating you mightnt be able to read Chinese datasheets, do the Chinese have an equivalent of eg the UCC28070 Dual  interleaved  PFC controller?

Or the Chinese have an equivalent of the LT8705 "Buck or Boost" controller?

..Which magically transitions from bucking to boosting and VV, whenever the vin and vout so dictate.

Or the magical high side gate driver by Infineon

....So do the Chinese have this kind of wonderful bootsrappable hi side, HV gate driver, which is wonderful for offline Bridges etc

....and are these devices, if they exist, for sale in the EU/USA/Aus/Jpn/West?

Or do all the Chinese's internal PSU's (for sale only inside China) use software controlled Power supply control chips?

I've been to the electronics markets in China.

It's safe to say that, counterfeits notwithstanding, Chinese government has ready access to the same commercial component inventory as Western electronics manufacturers.

In other words, there are no export restrictions on China.  Iran and North Korea are very different export situations.  Iran and NK will rely heavily on third parties to ship restricted electronics.
