The 12V Pico TLynxTM 6A module should be  
connected to a low ac-impedance source. A highly

inductive source can affect the stability of the  
module. An input capacitance must be placed  
directly adjacent to the input pin of the module, to  
minimize input ripple voltage and ensure module  
stability.

The 12V Pico TLynxTM 6A modules are designed for  
low output ripple voltage and will meet the maximum  
RLOAD  
output ripple specification with 0.1 µF ceramic and 10  
µF ceramic capacitors at the output of the module.  
However, additional output filtering may be required  
by the system designer for a number of reasons.  
First, there may be a need to further reduce the  
output ripple and noise of the module. Second, the  
dynamic response characteristics may need to be  
customized to a particular load step change.

polymer and ceramic capacitors are recommended to  
improve the dynamic response of the module. Figure
