Hi Sir,

what's your inductor saturation current? it may trigger the current limit.

Hi Sean:

Saturation Current : 900 mA ( max )

Hi Kevin,

Is the output current equal to the designed value? Or you can try with a higher saturation value inductor?

Hi Sir,

Increase the supply voltage that may help or you can choose TPS61165.
