Notes :
1. Specifications typical at Ta=+25], resistive load, nominal input voltage, rated output current unless otherwise noted.
2. Ripple & Noise measurement bandwidth is 0-20 MHz.
3. These power converters require a minimum output loading to maintain specified regulation.
4. Operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed.
5 All DC/DC converters should be externally fused at the front end for protection.
6. Other input and output voltage may be available, please contact factory.
7. Specifications subject to change without notice.
8. It is not recommended to use water-washing process on SMT units.

Test Configurations
Input Source Impedance
Input Reflected-Ripple Current Test Setup
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.
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.

Load
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.
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 input devices.

A good quality low ESR capacitor placed as close as
practicable across the load will give the best ripple and noise

To reduce output ripple, it is recommended to use 3.3uF
capacitors at the output.

Design & Feature Considerations
Maximum Capacitive Load
The MSLU100 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 33uF maximum
capacitive load.
The maximum capacitance can be found in the data sheet.

Thermal Considerations
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.
