Hi,

This information can be found in section 7 of the Product Specification.

The supply voltage range for DC/DC mode is 2.1 V to 3.6 V.

Best regards,

Øyvind

hi,you mean the voltage of AVDD is about 0v-1.8v when DCDC enabled? i know the post you suggested, i found that someone said AVDD is about 1.88v when DCDC enabled and another one said 800mV.... looks like it's not one certain value. so, i want to confirm the range of AVDD when DCDC enabled. does the output of internal DCDC depends on the input voltage? b/r
