Monotonic Start-up and Shutdown
The 12V Pico TLynx
start-up and shutdown behavior for any combination of
rated input voltage, output current and operating
temperature range.
Startup into Pre-biased Output
The 12V Pico TLynx
prebiased output as long as the prebias voltage is 0.5V
less than the set output voltage.
Power Good
The 12V Pico TLynx
Good (PGOOD) signal that is implemented with an
open-drain output to indicate that the output voltage is
within the regulation limits of the power module. The
PGOOD signal will be de-asserted to a low state if any
condition such as overtemperature, overcurrent or loss
of regulation occurs that would result in the output
voltage going ±12.5% outside the setpoint value. The
PGOOD terminal should be connected through a
pullup resistor (suggested value 100KΩ) to a source of
5VDC or lower.
Tunable Loop
The 12V 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 Fig. 52) 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
adjust the voltage control loop to match the filter
network connected to the output of the module. The
Tunable Loop
R-C between the SENSE and TRIM pins of the
module, as shown in Fig. 11. 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
and 3. Table 2 shows the recommended values of
R
capacitors up to 470uF that might be needed for an
application to meet output ripple and noise
requirements. Selecting R
Table 2 will ensure stable operation of the module.
In applications with tight output voltage limits in the
presence of dynamic current loading, additional output
capacitance will be required. Tables 3,4 and 5 list
recommended values of R
meet 2% output voltage deviation limits for some
common output voltages in the presence of a 1A to 2A
step change (50% of full load), for input voltages of
12V, 5V and 3.3V respectively.
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.
