Part Number: TPS61260

Hi All,

I attached a file that is schematics of TPS61260.

Input : 1.8V@200mA

Output : 1.8B@100mA

That is for Wearable Device.

Review my schematics , ASAP.

Best Regards,

Inho Jeon.

Your request is notified to the responsible TI engineer. He will response as soon as possible.

you need to add feedback resistors to set the output voltage to 1.8V.
why do you need a boost converter if the input is the same as output?

Dear Jasper,

I'd like to control another 1.8V power.

VDD_S is for vib.motor, +1.8V is for MCU systems.

What is the benefit of adding TPS61260 in your circuit? will the 1.8V drop down to lower voltage?

Dear Jasper,

Thank you for your reply.

In your reply, It is not proper way.
So, I discard that and designed by new ways.

Best regards,
