TPS61086: Is a Single Lithium ion Battery Suitable for Vin? Noise?

JonP

Other Parts Discussed in Thread: TPS61086

Can I use a single cell Lithium Ion Battery, (which will vary in voltage over the discharge cycle), to power the TPS61086?

Is there an issue with using a variable input and the forced PWM?

Can you provide a rough noise figure for this part?

Thanks,

Hi,

The battery discharge is not a noise input, this is a very normal condition, just DC voltage drops. So there will be no issue.

Could you please share the detailed application information for us? Like in what kind of equipment? Volume?You can send the information to me by email, my email address is helen-chen@ti.com.

Best regards,

helen
