Part Number: TPS61220

Hi TIer

We're using TPS61220.we need to get 1.6V output.（The minimum output is 1.8V in the datasheet）。

We have implemented a 1.6V output in the actual circuit when the input is 0.9v~1.45v。

Whether there is a hidden danger？

Hi Tony,

The internal circuit requires at least 1.8V to guarantee normal operation and control accuracy.
you can add schottky diode between the output of the converter and the loading to increase the VOUT voltage level.

hi Jasper
Thank you for your timely reply. This project is a low-power application add schott impact on power consumption。
would you please help recommend the output of 1.6V booster devices PN#, parameters similar to TPS61220,
Thanks！

Hi Tony

I can find TPS6100x may be suitable for your application. but the IQ is much larger than TPS61220.
