Detailed circuit description
In the following major buck regulator blocks, the linear voltage regulators and trackers,
the undervoltage reset function, the watchdog and the SPI are described in more detail.
For applications information e.g. choice of external components, please refer to
section .
2.1
Buck Regulator
The diagram below shows the internal implemented circuit of the Buck converter, i. e. the
internal DMOS devices, the regulation loop and the other major blocks.
Figure 3 Detailed Buck regulator diagram
The 1.5A Buck regulator consists of two internal DMOS power stages including a current
mode regulation scheme to avoid external compensation components plus additional
blocks for low EME and reduced switching loss. Figure 3 indicates also the principle how
