TPS61287: About VIN abs max and recommended operation rating..

Ernest Cho
Expert 3291 points
Part Number: TPS61287


Tool/software:

Hi team, 

I'd like to know if Vin is in between 23V to 30V? (and Vout is set to 24V) 

Is the internal HS FET bypassed? or turned off?

One of my customer concerned in case of battery ranged 17.4V(min) ~ 25.2V(max).

Thank you.

Ernest Cho.

    Hi Ernest,

    On this condition, the body diode of HS FET would be turned on. But the device don't have VIN over voltage protection, it is not recommend to make TPS61287 operating with voltage > 23V.

    Regards,
