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. 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 oper ated in current limiting mode during start-up, affecti ng the ramp-up and the startup time. for optimum performance we recommend 390uf maximum capacitive load for dual outputs and 470 u f 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 st ability 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 t he 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 orientat ion, airflow over the module and board spacing. to avoid exceeding the maximum temperature rating of t he components inside the power module, the case temperatur e must be kept below 90c. the derating curves are det ermined from measurements obtained in an exper imental apparatus. mau300 series rev:0 2005/04 minmax 5 +out -out +vin -vin dc / dc converter load battery + lin + cin to oscilloscope current probe +out -out +vin -vin dual output dc / dc converter resistive load scope copper strip cout com. scope cout +out -out +vin -vin single output dc / dc converter resistive load scope copper strip cout + +out -out +vin -vin dc / dc converter load dc power source + - cin +out -out +vin -vin load dc power source + - cout com. dual output dc / dc converter +out -out +vin -vin load dc power source + - cout single output dc / dc converter dut position of air velocity probe and thermocouple 50mm / 2in air flow 15mm / 0.6in
