Typical Connection of Boost Converter.
When the boost converter is not connected the microcontroller can be powered directly from an
external source and is then subject to the standard supply voltage limits defined in “Electrical
It is recommended to use the Brown-out Detection (BOD) circuit only with the lowest BOD level
(1.8V), when using the integrated boost converter. This is because supply voltage of the micro-
controller can drop to lowest BOD levels during regular operation. See “Brown-out Detection” on
8.2
Modes of Operation
The boost converter has three main modes of operation; Stop, Start, and Active. Operation
begins from Stop Mode and is transferred to Start Mode when input voltage, V
BAT, is sufficiently
high for stable operation. When the converter has managed to raise the output voltage, V
CC, to a
sustainable level control is then transferred to the main mode of operation, Active Mode.
The modes of operation are illustrated in Figure 8-3, below.
