Tunable Loop
The 5V Pico TLynx
that optimizes transient response of the module called
Tunable Loop
External capacitors are usually added to the output of
the module for two reasons: to reduce output ripple and
noise (see Figures 36 and 37) and to reduce output
voltage deviations from the steady-state value in the
presence of dynamic load current changes. Adding
external capacitance however affects the voltage control
loop of the module, typically causing the loop to slow
down with sluggish response. Larger values of external
capacitance could also cause the module to become
unstable.
The Tunable Loop
the voltage control loop to match the filter network
connected to the output of the module. The Tunable
Loop
between the SENSE and TRIM pins of the module, as
shown in Fig. 44. This R-C allows the user to externally
adjust the voltage loop feedback compensation of the
module.

module.
Recommended values of R
output capacitor combinations are given in Tables 2, 3,
4 and 5. Tables 2 and 4 show the recommended values
of R
capacitors up to 940μF that might be needed for an
application to meet output ripple and noise requirements
for 5Vin and 3.3Vin respectively. Selecting R
C
of the module.
In applications with tight output voltage limits in the
presence of dynamic current loading, additional output
capacitance will be required. Tables 3 and 5 list
recommended values of R
meet 2% output voltage deviation limits for some
common output voltages in the presence of a 1.5A to 3A

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 5 or
3.3V.
