Page 7 - DESIGN CONSIDERATIONS; Input Source Impedance

DS_S48SP05007_05222008 7 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...

Page 8 - FEATURES DESCRIPTIONS; Over-Current Protection

DS_S48SP05007_05222008 8 FEATURES DESCRIPTIONS Over-Current Protection The modules include an internal output over-current protection circuit, which will endure current limiting for an unlimited duration during output overload. If the output current exceeds the OCP set point, the modules will automa...

DS_S48SP05007_05222008 9 FEATURES DESCRIPTIONS (CON.) Output Voltage Adjustment To increase or decrease the output voltage set point, the modules may be connected with an external resistor between the TRIM pin and either the Vo(+) or Vo(-). The TRIM pin should be left open if this feature is not use...
