DS_E48SB12020_05222008 7 DESIGN CONSIDERA TIONS Input Source Impedance The impedance of the input sou rce connecting to the DC/DC powe r modules will interact wit h the modules and affect the st ability . A low ac-impe dance input source is recommended.
DS_E48SB12020_05222008 8 Over-T emp erature Protection The over-temperature protection consists of circuitry t hat provides protection from therm al damage. If the temperature exceeds the over-t em perature threshold, the module will be shut down, and enter in the auto-rest art mode or latch mode, which is optional.
DS_E48SB12020_05222008 9 THERMAL CONSIDERA TIONS Thermal management is an importa nt part of the system design. To ensure prop er, reliable operation, sufficie nt cooling of the power mod ule is needed over the entire temperature range of the modul e.
