Pager baseband controller

PCA5010

Fig.51 Supply current in normal mode.

VDD = 2.2 V, microcontroller idle, all functions disabled.

Note: This curve cannot be directly measured by varying VBAT, because the shown current is the battery current in discontinuous mode.

Changing the battery voltage can force the DC/DC converter to enter continuous mode.

At a given battery voltage a mode change from continuous to discontinuous mode happens only after a load reduction.
