Hi,

I can not enable DC DC when I have the load current more than 0.6A. I use RIGOL DC-load?

Reg,

Hi Kawa,

TPS61022 has limited about 700mA start-up strength before Vout reaches to 0.4V. After it ramps up to 0.4V above, it has ability to drive 1ohm load. Please do not put load before TPS61022 is enabled.
