Tunable Loop
The 12V Micro TLynx
feature 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 Figure 41) 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. 48. This R-C allows the user to externally
adjust the voltage loop feedback compensation of the
module.
Recommended values of R
output capacitor combinations are given in Tables 2 and
3. Table 2 shows the recommended values of R
C
up to 940μF that might be needed for an application to
meet output ripple and noise requirements. Selecting

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 6A to 12A step change
(50% of full load), with an input voltage of 12V.
