巴克直流-直流转换器4.5 v:怎么了?

Good day,
I would like to know how can I get a regulated voltage of 4.5V out of the DA14680 to power an external device. I am not seeing how to do so in the datasheet/ appnotes provided. From what I see the Buck converter is linked to the VDD, V18, V18P or V14 outputs. However, I am not seeing how can I get such a voltage at any of these outputs.
Thanks in advance.

Hi aaron.roopnarine,

Hi aaron.roopnarine,

Where exactly did you see that the DCDC is able to provide that kind of voltage ? The DCDC operates only in BUCK mode and has a range of configurable voltages from 1.2 up to 2V with 25mV step.

Thanks MT_dialog

Check the first page of the

Check the first page of the DA14680 specification sheet. Under the "Features" heading, "Power Management" subheading, it specifically states "Integrated Buck DC-DC converter (1.7 V to 4.5 V)". Obviously one would want to know how I am getting access to this voltage to power an external load. I am still yet to see why. You only stated the ability of the DC-DC converter to deliver up to 2V.

Hi aaron.roopnarine,

Hi aaron.roopnarine,

This is the supply voltage that the buck DCDC is able to operate via the VBAT not the range of the output voltage of the DCDC.

Thanks MT_dialog
