Design Considerations
Input Reflected Ripple
An internal aluminum electrolytic input capacitor is
used for filtering; therefore, input ripple increases as
temperature decreases. There is approximately two
times more ripple at 0 °C than at 25 °C and eight times
more ripple at –40 °C than at 25 °C. The power module
functions properly down to –40 °C with no additional
filtering. If lower ripple comparable to that at 25 °C is
needed at low temperatures, an external capacitor
across the input with an impedance of 0.5
over the desired temperature range is recommended.
See Figure 24 for the test setup.
