TPS62811-Q1: Undervoltage Lockout - Threshold Voltage at EN-pin?

Diego Dolp

Part Number: TPS62811-Q1

Dear team,

I'm confused by the UVLO-information given in the TPS62811-Q1's data sheet. On p. 6, I find:

Whereas p. 12 states:

What is the EN pin's threshold-voltage above which the converter starts powering up, 1.1 V or 2.6 V?

Thanks in advance for your support. Kind regards,

Diego

HI Diego,

Thanks for your question.

In general, the 1.1V refers to the EN pin, while the 2.6V (UVLO) refers to the VIN pin. You need both conditions to start up the device.

Thanks,

Stefano
