Re: 7055-D current capacity for DC-DC converter

Thx, it aligns with my observation. I use aux power for my purposes but I've tried once to power a device with a known demand for current of almost 500 mA and it couldn't boot when powered directly by 7055-D.

7055-D current capacity for DC-DC converter

Hi,

Is it normal that 7055-D cannot provide more than 410 mA of current? For 430 mA output voltage of my unit drops below 4V. The USB hub which powers the isolator can provide more than 1A over the usb port.

Re: Model 7055-B Output Current Capability

Is this - "the AUX will be switched to the device port directly using a relay, effectively disabling the internal regulator", I guess no filtering at all - valid also for 7055-D? If so, how the current is limited to 2000mA? This is also valid for the 7055-D. The output current is limited by using a...
