Figure. 28. Circuit diagram showing connection of
R
module.
Recommended values of R
output capacitor combinations are given in Tables 2 and
3. Table 2 shows the recommended values of R
C
to 2000uF that might be needed for an application to
meet output ripple and noise requirements. Selecting
R
operation of the module.
In applications with tight output voltage limits in the
presence of dynamic current loading, additional output
capacitance will be required. Table 3 lists recommended
values of R
voltage deviation limits for some common output voltages
in the presence of a 25A to 50A step change (50% of full
load), with an input voltage of 12V.
Please contact your Lineage Power technical
representative to obtain more details of this feature as
well as for guidelines on how to select the right value of
external R-C to tune the module for best transient
performance and stable operation for other output
capacitance values or input voltages other than 12V.
