TPS63070: May we have solution can support 5Vin /Vout 20V Iout 20mA power solution?

Hi Sir

May we have solution can support 5Vin /Vout 20V Iout 20mA power solution? but out voltage is Dynamically Adjustable Output. Range from 7V~20V (Vout change by I2C control 255steps /output current under 20mA)

May you have suggestion part? or we can use boost D2D + DAC to finish this kind design. if yes, may we have reference circuit?

Hi Bogey,

To summarize, you need to convert Vin=5 V to Vout=7-20 V at Iout=20 mA? If so, you are better off using a boost converter. The TPS63070 is a buck-boost converter. It can work as a boost converter only, but the maximum output voltage is limited to 9 V.

Hi Milos

thanks for your reply~

So, we currently have no suit part for this kind application. right?

Hi Bogey,

There should be a suitable part, I will ask our boost engineers.

Hi Bogey,
you can use a boost converter TPS61170, and PWM on the CTRL pin to set the output voltage
