Page 6 - DESIGN CONSIDERATIONS; Input Source Impedance

DS_S48SE05003_12292006 6 DESIGN CONSIDERATIONS Input Source Impedance The impedance of the input source connecting to the DC/DC power modules will interact with the modules and affect the stability. A low ac-impedance input source is recommended. If the source inductance is more than a few µ H, we a...

DS_S48SE05003_12292006 9 Thermal Derating Heat can be removed by increasing airflow over the module. To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit m...
