  • RE: TPS61166: TPS61166 running off a single cell LiIon?

    Hi Balaji, Vbat could be tied to Vin and supplied by 3.3V to 4.2V input voltage. Another suggestion for your application is TPS61158, it is also a synchronized boost converter but less pin numbers and easy to use.

  • RE: TPS61169: Could you tell me about "TPS61169's DIM pin=L MODE"?

    Hi Masumi-san, If you are looking for synchronous device, please also take a look ar TPS61158. May I know what is yoru application? who is the end customer and what is the end equipment? thanks.
