Current and Voltage specification about VBAT3V in boost mode

Hello to all,
I need to power an IC sensor with button batteries.

I see that DA14580 has DCDC converter inside. I read the datasheet but I find no clear specifications about Vout and maximum Iout that DCDC is capable of supply from VBAT3V pin.

The IC sensor requires a voltage range of 2.8-3.3 to work and needs 20mA of supply current. I turn on the sensor only when I need to read it otherwise is always off.

So can I supply this sensor by DA14580 DCDC converter?

Thanks

Hello Giuseppe, unfortunately

Hello Giuseppe, unfortunately this generatio of DA14580 is not able to supply that amount of current : the dc-dc is only designed to power the device and not peripherals. Best regards JE_Dialog
