MIW2000 SeriesTest ConfigurationsInput Reflected-Ripple Current Test SetupInput reflected-ripple current is measured with a inductorLin (4.7uH) and Cin (220uF, ESR < 1.0[ at 100 KHz) tosimulate source impedance.Capacitor Cin, offsets possible battery impedance.Current ripple is measured at the input terminals of themodule, measurement bandwidth is 0-500 KHz.Overcurrent ProtectionTo provide protection in a fault (output overload) condition,the unit is equipped with internal current limiting circuitry andcan endure current limiting for an unlimited duration. At thepoint of current-limit inception, the unit shifts from voltagecontrol to current control. The unit operates normally once theoutput current is brought back into its specified range.Input Source ImpedanceTo Oscilloscope+ + LinBatteryCinCurrentProbe+Vin+OutDC / DCConverter-Vin-OutLoadThe power module should be connected to a lowac-impedance input source. Highly inductive sourceimpedances can affect the stability of the power module.In applications where power is supplied over long lines andoutput loading is high, it may be necessary to use a capacitorat the input to ensure startup.Peak-to-Peak Output Noise Measurement TestUse a Cout 0.47uF ceramic capacitor.Scope measurement should be made by using a BNCsocket, measurement bandwidth is 0-20 MHz.

MIW2000 SeriesThermal ConsiderationsMany conditions affect the thermal performance of thepower module, such as orientation, airflow over the moduleand board spacing. To avoid exceeding the maximumtemperature rating of the components inside the powermodule, the case temperature must be kept below 90°C.The derating curves are determined from measurementsobtained in an experimental apparatus.Position of air velocityprobe and thermocouple15mm / 0.6in50mm / 2inAir FlowDUT7MINMAXREV:0 2005/04
