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. 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. Design & Feature Considerations Maximum Capacitive Load The MAU300 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 390uF maximum capacitive load for dual outputs and 470uF capacitive load for single outputs. The maximum capacitance can be found in the data sheet. 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. 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 comended 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. Output Ripple Reduction 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 1.5uF capacitors at the output. 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.

The MAU300 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. 2.7g:Weight +Vout+Vout6 CommonNo Pin5 Non-Conductive Black Plastic:Case Material -Vout-Vout4 -Vin-Vin2 0.77*0.30*0.40 inches+Vin+Vin1 19.5*7.6*10.2 mm:Case Size Dual OutputSingle OutputPin Physical CharacteristicsPin Connections {0.002{0.05Pin X.XXX{0.005X.XX{0.13 X.XX{0.01X.X{0.25 InchesMillimetersTolerance Dual Output Single Output 19.5 [0.77] 10.2 [0.40] 3.2 [0.13] 0.5 [0.02] 2.3 [0.09] 1.3 [0.05] 18.5 [0.73] 12 456 7.6 [0.30] 2.54 [0.100] 0.25 [0.010] 0.50 [0.020] Connecting Pin Patterns Bottom View ( 2.54 mm / 0.1 inch grids ) Mechanical Dimensions MAU300 Series 6MINMAXREV:0 2005/04
