MIW5000 SeriesTest ConfigurationsInput Reflected-Ripple Current Test Setup

Input reflected-ripple current is measured with a inductorLin (4.7uH) and Cin (220uF, ESR < 1.0[ at 100 kHz) tosimulated source impedance.

Capacitor Cin, offsets possible battery impedance.Current ripple is measured at the input terminals of themodule, measurement bandwidth is 0-500KHz.

To Oscilloscope+Battery+LinCurrentProbe+Vin+Outcontrol to current control. The unit operates normally once theoutput current is brought back into its specified range.

Overvoltage ProtectionThe output overvoltage clamp consists of control circuitry,which is independent of the primary regulation loop, thatmonitors the voltage on the output terminals.

The control loop of the clamp has a higher voltage setpoint than the primary loop.

This provides a redundant voltage control that reduces therisk of output overvoltage.

LoadCinPeak-to-Peak Output Noise Measurement Test

Use a Cout 0.47uF ceramic capacitor.

Scope measurement should be made by using a BNCsocket, measurement bandwidth is 0-20 MHz. Position theload between 50 mm and 75 mm from the DC/DC Converter.

+VinSingle OutputDC / DCConverter-Vin-Out+OutCopper StripCoutScopeResistiveLoadThe 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 capacitoron the input to insure startup.

By using a good quality low Equivalent Series Resistance(ESR < 1.0[ at 100 kHz) capacitor of a 12uF for the 12V,4.7uF for the 24V input devices and a 2.2uF for the 48V

devices, capacitor mounted close to the power module helpsensure stability of the unit.

To reduce output ripple, it is recommended that 3.3uFcapacitors are used on output.

MIW5000 SeriesThermal ConsiderationsMany conditions affect the thermal performance of thepower module, such as orientation, airflow over the module,and board spacing. To avoid exceeding the maximumtemperature rating of the components inside the powermodule, the case temperature must be kept below 95°C.

The derating curves were determined from measurementsobtained in an experimental apparatus.
