Output Ripple Reduction 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. +Vin 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. Resistive Load 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. + +Vin Single Output DC / DC Converter DC Power Source Cout Scope Cout Scope Cout - -Vin -Out + +Vin +Out Load Dual Output DC / DC Com. Converter DC Power Source - Copper Strip +Out -Vin Cout Load -Out Thermal Considerations Resistive Load Design & Feature 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 95°C. The derating curves are determined from measurements obtained in an experimental apparatus. 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. 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.
