DPM Functions
10.3.1 POL Programming
POL programming is the process of downloading the content of POL setup registers stored in DPM’s
non-volatile memory via the SD bus to the POL converters.
Programming of POL converters is performed upon power-up, or when the Program Config… button is
pressed in the GUI System Configuration window shown in Figure 9, or when the specific command is
sent directly via the I 2 C bus.
Figure 9. System Configuration Window
The programming is performed in several steps. Once the supply voltage on the VDD pins of the DPM
exceeds the UVLO protection threshold, the DPM will start copying setup registers from its non-volatile
memory into RAM and execute the cyclic redundancy check (CRC) to ensure integrity of the
programming data. When the voltage on the IBVS pin exceeds the IBV undervoltage protection
threshold, the DPM will download POL setup registers to the respective POL converter via the SD line.
Every data transfer is protected by parity check and followed by the POL acknowledgement and read
data back procedure. If both acknowledgement and readback operations are successful, the POL-
