TPS61094: TPS61094 max output current in buck/boost and bypass mode

Other Parts Discussed in Thread: TPS631000,

Hello,

 

I have another question on TP61094 :

 

  • Can you confirm in bypass mode it’s possible to pass 1,2 A through the internal Mosfet ?

(Vin 5V4 -> Vout 5V4 1,2A)

  • And same question in Buck mode 

(Vin 5V4 -> Vout 3V4 1,2A)

It seems to be ok, but if you can confirm,

Thanks a lot for your answer,

Regards

    Hi Vincent,

    1.2A is possible. Please note in force bypass mode the Vout will be 5.4-1.2A*120mOhm=5.256V.

    The maximum charge current for buck_on mode is 600mA.

    TPS61094 is a bi-directional buck-boost converter designed for backup applications. If you are finding a device which is a truly buck/boost converter, you may need to check TPS631000.
