Design Considerations
The Austin MegaLynx
a low-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, low-ESR ceramic
capacitors are recommended at the input of the module.
Figure 41 shows the input ripple voltage for various
output voltages at 25A of load current with 2x22 µF or
4x22 µF ceramic capacitors and an input of 12V. Figure
42 shows data for the 5Vin case, with 2x47µF and
4x47µF of ceramic capacitors at the input, and for a load
current of 30A.

voltages with 2x22 µF or 4x22 µF ceramic capacitors
