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 recommended 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 input devices. + DC Power Source + Cin -Vin -Out +Vin DC / DC Converter +Out Load DC / DC Converter -Vin -Out Cin + +Vin Single Output DC / DC Converter -Vin +Out Peak-to-Peak Output Noise Measurement Test Use a Cout 0.47uF ceramic capacitor.

Copper Strip Cout Cout Scope Resistive Load Scope DC Power Source - -Out Cout Load Design & Feature Considerations Maximum Capacitive Load The MDHU100 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 330uF capacitive load for single outputs. The maximum capacitance can be found in the data sheet. + DC Power Source -Vin +Vin +Out Dual Output Com. DC / DC Converter -Out Cout Load 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. 5 MINMAX REV:5 2009/01/16 MDHU100 Series 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.
