10.2 POL Monitoring
Z-series POL converters can monitor own performance parameters such as output voltage, output current, and
temperature. Monitored parameters are stored in POL registers VOM, IOM, and TMON that are continuously
updated. If monitoring is enabled, the DPM will be continuously copying POL status and parametric data into
monitoring data registers. There are two blocks of POL monitoring memory as shown in Table 3. The first block
contains 32 bytes representing the status registers of all POL converters. The second block contains monitoring
data for each POL converter output voltage, output current, and temperature. For each parameter there is a ring
buffer of 10 most recent values (3x10 values times 32 POLs=960 Bytes).
