Hi,
I'm Daniel from M2comm.
I had a question about TPS610986 :
I'd like to know its max output current for Vsub, I do know Vmain is 350~650mA, but Ican't find out detailed value about Vsub.

Hi Yujen:
The minimal value of the Vsub current limit is 200mA. It's in the Page 6 of the datasheet.
Actually, the limit of the Vmain is not 350-650mA. "350-650 mA" is the peak current limit of the inductance. It will take load of Vmain, Vsub into considered together.
Hi Minqiu,
Thanks.
I can calculate Iout by using this formula : Iout=[Vin*(Ilim-50mA)*80%]/Vmain, was I right? (I assumed the efficiency was 80%.and Iout=Imain=Isub)
Hi YuJen:
Almost right. Just two points need to be clarify:
1. 100mA as the current ripple of the inductance is typical value.
2. Iout should be Iout=Imain+Isub. Meantime, Isub will be limited below 200mA specifically.
