TPS61041: Rise time vs inrush current

Michael Balourdas

Part Number: TPS61041

Hello,

For this device, how is the output voltage rise time affected by inrush current? For example, if I have a load switch limiting the inrush current to 150mA, how much variance could I see in the rise time of Vout?

Thanks,

Michael

Hi Michael,

Is the load switch at the input side? What's the Vin/Vout/Load condition?

Hi Zack,

Yes, the load switch is at the input side.

5Vin, 25Vout, 700mA out.

Thanks,

Michael

Hi Michel,

Actually it's to hard to say the startup behavior if you limit the input current, it's related to input caps, output caps, the feature of input power source... Maybe a bench test is a more convenient way to ensure this.
