Other Parts Discussed in Thread: TPS62110, TPS62160, TPS62130

Hi Team,

I'd like to ask about TPS62110 series.

Input voltage range of TPS62110 is listed with 3.1V-17V.

However, UVLO is 2.8V - 3.1V.

Furthermore,

UVLO is written to the data sheet when it comes to the worst case 3.4V.

Vin (min) is whether it is better to think with 3.4V?

Could you tell me the meaning of worst-case?

Best Regards,

You are correct. Once it has started operation, the TPS62110 will continue to operate at Vin input voltages as low as 3.1 V. But in some devices, you may need at least 3.4 V on the input to start up. That is the worst case , typically you will need 3 + .250 = 3.25 V on the input to start.

I would recommend you look at the TPS62130 and/or TPS62160 instead of the older TPS62110. They are smaller and can start from 3V.
