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.

Input Source Impedance

Test Configurations

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 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.

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.

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.
