Performance Parameters Monitoring
The POL converters are equipped with the digital
current share function. To activate the current share,
interconnect the CS pins of the POLs connected in
parallel. The digital signal transmitted over the CS
line sets output currents of all POLs to the same
level.
When POLs are connected in parallel, they must be
included in the same parallel bus in the GUI System
Configuration window shown in Figure 53. In this
case, the GUI automatically copies parameters of
one POL onto all POLs connected to the parallel
bus. It makes it impossible to configure different
performance parameters for POLs connected in
parallel except for interleave and load regulation
settings that are independent. The interleave allows
to reduce and move the output noise of the
converters connected in parallel to higher
frequencies as shown in Figure 49 and Figure 50.
The load regulation allows controlling the current
share loop gain in case of small signal oscillations. It
is recommended to always add a small amount of
load regulation to one of the converters connected in
parallel to reduce loop gain and therefore improve
stability.
The POL converters can monitor their own
performance parameters such as output voltage,
output current, and temperature.
The output voltage is measured at the output sense
pins, output current is measured using the ESR of
the output inductor and temperature is measured by
the thermal sensor built into the controller IC. Output
current readings are adjusted based on temperature
readings to compensate for the change of ESR of
the inductor with temperature.
An 8-Bit Analog to Digital Converter (ADC) converts
the output voltage, output current, and temperature
into a digital signal to be transmitted via the serial
interface. The ADC allows a minimum sampling
frequency of 1 kHz for all three values.
Monitored parameters are stored in registers (VOM,
IOM, and TMON) that are continuously updated. If
the Retrieve Monitoring bits in the GUI Group
Configuration window shown in Figure 54 are
checked, those registers are being copied into the
ring buffer located in the DPM. Contents of the ring
buffer can be displayed in the GUI IBS Monitoring
Window shown in Figure 55 or it can be read directly
via the I 2 C bus using high and low level commands
as described in the ‘”DPM Programming Manual”.
