TPS63070: Start-Up Issue TPS63071

user4136264

Part Number: TPS63070

Hi,

i have desgined a Power Supply with the IC TPS63071 (Fixed 5V Version) it works well so far, exept one topic:

when I apply the supply voltage to the TPS63071 device and there is an ohmic load of less than 7Ohm at the output, the output voltage no longer reaches 5V.
If I switch the load off and on again, the output voltage is back at 5V as expected.

Regards,

Thomas

Hi Thomas,

The start up current is lower than the normal operation current. Please check the below picture:
