Test Configurations

In applications where power is supplied over long lines andoutput loading is high, it may be necessary to use a capacitor
at the input to ensure startup.

Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with a inductor
Lin (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.

Capacitor mounted close to the power module helps
ensure stability of the unit, it is commended to use a goodquality low Equivalent Series Resistance (ESR < 1.0[ at 100KHz) capacitor of a 2.2uF for the 5V input devices, a 1.0uF forthe 12V,15V input devices and a 0.47uF for the 24V devices.

A good quality low ESR capacitor placed as close aspracticable across the load will give the best ripple and noiseperformance.
To reduce output ripple, it is recommended to use 1.0uF
capacitors at the output.

Thermal Considerations

Maximum Capacitive Load
The MAU100 series has limitation of maximum connected
capacitance at the output.
The power module may be operated in current limitingmode during start-up, affecting the ramp-up and the startup
time.
For optimum performance we recommend 100uF
maximum capacitive load for dual outputs and 220uF
capacitive load for single outputs.
The maximum capacitance can be found in the data sheet.

Many conditions affect the thermal performance of thepower module, such as orientation, airflow over the moduleand board spacing. To avoid exceeding the maximum
temperature rating of the components inside the powermodule, the case temperature must be kept below 90°C.
The derating curves are determined from measurements
obtained in an experimental apparatus.

The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the power module.

The MAU100 converter is encapsulated in a low thermal resistance molding compound that has excellent resistance/electricalcharacteristics over a wide temperature range or in high humidity environments.
The encapsulant and unit case are both rated to UL 94V-0 flammability specifications.
Leads are tin plated for improved solderability.
