TPS81256: Start-up without resistive load possible?

Franz Schellhase

Part Number: TPS81256

Hi team,

The datasheet of TPS81256 states that the minimum resistive load for start-up is 65 Ohm. Does this mean without a load the device won't start? Is there a way to make it work without the load?

Thank you,

Franz

Hi Franz,

it means the load can't be too large (small resistor), otherwise the device can't startup because of the current limitation during startup
