I'd place my bids on TPS61170 as compatible.
I didn't check the pinout against what is on the S5 board, but it's the only one I've found in 6 pins package with specifications that would match the part on board regarding Vin and Vout.
The device marking is supposed to be BZS, but maybe the one on the S5 board is simply a clone from another manufacturer.

Am away from Home, but looking at a picture of an S5 Hash Board the Pinout ties up with the TPS61170, so I think a good call.

After checking the S5 board it looks 90% that TPS61170 belong to U101 ( step up voltage) for S5 hashboard

Nice, don't forget that if you replace U101 with TPS61170, 5% of the hashrate from your S5 will mine directly to my BTC address Grin

I have a few S5 boards that failed after a shortcircuit, never had the time to check what was wrong, I'll start with U101 output.
