DA9070巴克调节器上启用升高?

Just want to verify that the buck converter is enabled by default on power-up. On page 106 of the datasheet, Buck Enable is shown to be a zero on power-up. Should this be described as a "Buck Enable Not" function? A zero in bit 7 of register 0x0030 enables the buck output? I assume the default output is 2.0V. Thanks.

Device:

DA14580

Hello,

Hello,

The DA9070/73 are OTP programmed devices, so the set-up of the device is dependent on the OTP configuration. whether the buck is enabled and what output voltage it is set to is dependent on the OTP settings. Our demo boards have the Buck enabled by default, however it is possible and to have the Buck disabled by default and set to different voltages.

Kind regards,
Elliott
