TPS61391: What is the output current rating?

John Smith

Part Number: TPS61391

Hi Team,
I'm wondering what is the output current max of this IC.

The datasheet so an example with few mA output APD.

But the Ilim can bet set very high, hundreds of mA. 

Can TPS61391 deliver 1A at 75V? Thanks.

    Hi John,

    Sorry, TPS61391 cannot deliver 75V,1A at output. TPS61391 typical Peak switching current limit is 1000mA which corresponds to peak input current. Output current max also depends on input voltage, input current ripple, efficiency, and output voltage.

    Best Regards,
