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.
Exceeding the absolute maximum ratings of the unit could cause damage. These are not continuous operating ratings.

Test Configurations
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.
To Oscilloscope + Battery + Lin Current Probe +Vin +Out 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 commended 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,15V 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 socket, measurement bandwidth is 0-20 MHz. Position the load between 50 mm and 75 mm from the DC/DC Converter.

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
The MAU100 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.
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 90C. 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.
