Design Considerations
Input Filtering
The 12V Pico TLynx
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.
To minimize input voltage ripple, ceramic capacitors
are recommended at the input of the module. Figure
40 shows the input ripple voltage for various output
voltages at 2A of load current with 1x10 µF or 1x22
µF ceramic capacitors and an input of 5V. Figure 41
shows the input ripple voltage for an input of 12V

voltages with 1x10 µF or 1x22 µF ceramic
capacitors at the input (2A load). Input voltage is
