QPO Applications
Figure 9 - QPO’s output voltage regulated by SC circuit.
In Figure 9, the QPO-1’s SC function is used to adapt the
converter’s output voltage to compensate for the headroom
voltage drop across the QPO-1. The SC function sources a
programmed current into the SC/Trim pin of the converter,
raising its reference voltage so that the converter’s output
voltage is increased by the amount of the headroom voltage.
The current is programmed via the RSCSET resistor and RSL is
used to limit the current during start-up to prevent over-
driving the converter.
Figure 10 shows the converter adapting for the QPO-1’s
headroom voltage drop by using its own remote sensing pins.
When using remote sensing, it is recommended to use the RC
network (RRS and CRS) to provide the feedback to the
positive sense pin to maintain converter stability.
These
values are recommended for the Vicor family of converters
using short, low parasitic, connections to the point of load.
They may have to be adjusted for other converters or for very
long or high parasitic connections to the load.
In both circuits; RHR, RP and CESR are vital components
required for proper operation. RSA, CP and CHR are optional
components that may or may not be required. The QPO-1 is
not designed to be paralleled to increase the rated current
limit of the filter.
