7.8 VPOL5A-5-SIP Series Output Voltage Adustment.
The output Voltage of the VPOL5A-5-SIPS33A can be adjusted in the
range 0.75V to 3.63V by connecting a single resistor on the
motherboard (shown as Rtrim) in Figure 12v. Whe n Trim resistor is not
connected the output voltage defaults to 0.75V
The value of Rtrim-up defined as:
Where: Rtrim-up is the external resistor in ohm,
To give an exa mple of the above calculation, to set a voltage of 3.3
Vdc, Rtrim is given by:
Rtrim = 3153 ohm
For various output values various resistors are calculated and provided
in Table 3 for co nvenience.

7.9 Output Ripple and Noise Measurement
The test set-up for noise and ripple measurements is shown in Figure
18. a coaxial cable with a 50ohm termination was used to prevent
impedance mismatch reflections disturbing the noise readings at
higher frequencies5^
7.10 Output Capacitance
V-Infinity’s VPOL5A-5-SIP series converters provide unconditional
stability with or without external capacitors. For good transient
response low ESR output capacitors should be located close to the
point of load.
For high current applications point has already been made in layout
considerations for low resistance and low inductance tracks.
Output capacitors with its associated ESR values have an impact on
loop stability and bandwidth. V-Infinity’s converters are designed to
work with load capacitance up-to 3,000 μF. It is rec ommended that any
additional capacitance, Maximum 3,000 μF and low ESR, be
connected close to the point of load and outside the remote
compensation point.
