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 +Vin Lin Current Probe Cin + +Out DC / DC Converter -Vin 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.

To reduce output ripple, it is recommended to use 1.5uF capacitors at the output. Scope Scope Cout Scope + +Vin Cout Load -Out +Out Dual Output DC / DC Com. Converter -Vin Cout Load -Out Thermal 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. 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. Position of air velocity probe and thermocouple 15mm / 0.6in 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. 5 -Vin - Design & Feature Considerations Input Source Impedance - DC Power Source Resistive Load +Out Single Output DC / DC Converter DC Power Source Resistive Load Copper Strip Cout +Vin MINMAX 50mm / 2in Air Flow DUT REV:0 2005/04 MAU300 Series Mechanical Dimensions Connecting Pin Patterns Bottom View ( 2.54 mm / 0.1 inch grids ) Single Output 3.2 [0.13] 10.2 [0.40] 0.5 [0.02] 19.5 [0.77] 2.54 [0.100] 2.3 [0.09] Dual Output 4 5 6 0.50 [0.020] Tolerance Pin 1.3 [0.05] 2 0.25 [0.010] 1 7.6 [0.30] 18.5 [0.73] Millimeters Inches X.X{0.25 X.XX{0.01 X.XX{0.13 {0.05 X.XXX{0.005 {0.002 Pin Connections Physical Characteristics Pin Single Output Dual Output 1 +Vin +Vin 2 -Vin -Vin 4 -Vout -Vout 5 No Pin Common 6 +Vout +Vout 19.5*7.6*10.2 mm Case Size : Case Material : Non-Conductive Black Plastic Weight : 2.7g 0.77*0.30*0.40 inches 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.
