Power Good
The SLIN-03E1Ax modules provide a Power 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 over temperature, over current or loss of regulation
occurs that would result in the output voltage going ±10% outside the set-point value. The PGOOD terminal
should be connected through a pull-up resistor (suggested value 100K
Ω) to a source of 5VDC or lower.
Tunable LoopTM
The SLIN-03E1Ax modules have a new feature that optimizes transient response of the module called Tunable
Loop
TM.
External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and
noise 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
TM allows the user to externally adjust the voltage control loop to match the filter network
connected to the output of the module. The Tunable Loop
TM is implemented by connecting a series R-C
between the SENSE and TRIM pins of the module, as shown below. This R-C allows the user to externally
adjust the voltage loop feedback compensation of the module.

Circuit diagram showing connection of RTUNE and CTUNE to tune the control loop of the module
Recommended values of RTUNE and CTUNE for different output capacitor combinations are given in below Tables
2 and 3. Table 2 shows the recommended values of RTUNE and CTUNE for different values of ceramic output
capacitors up to 470uF that might be needed for an application to meet output ripple and noise requirements.
Selecting RTUNE and CTUNE according to 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. Table 3 lists recommended values of RTUNE and CTUNE in order to meet 2% output
voltage deviation limits for some common output voltages in the presence of a 1.5A to 3A step change (50% of
full load), with an input voltage of 12V.
