Test Configurations
In applications where power is supplied over long lines and
output 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) to
simulate source impedance.
Capacitor Cin, offsets possible battery impedance.
Current ripple is measured at the input terminals of the
module, measurement bandwidth is 0-500 KHz.

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

Peak-to-Peak Output Noise Measurement Test
Use a Cout 0.33uF ceramic capacitor.
Scope measurement should be made by using a BNC

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

Design & Feature Considerations
Maximum Capacitive Load
Thermal Considerations
The MAU200 series has limitation of maximum connected
capacitance at the output.
The power module may be operated in current limiting
mode 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 the
power module, such as orientation, airflow over the module
and board spacing. To avoid exceeding the maximum
temperature rating of the components inside the power
module, the case temperature must be kept below 90°C.
The derating curves are determined from measurements
obtained in an experimental apparatus.
Input Source Impedance
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 MAU200 converter is encapsulated in a low thermal resistance molding compound that has excellent resistance/electrical
characteristics 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.
