Test Configurations Input Reflected-Ripple Current Test Setup Input reflected-ripple current is measured with a inductor Lin (4.7uH) and Cin (22uF, ESR < 1.[ at 1 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 - KHz. To Oscilloscope Peak-to-Peak Output Noise Measurement Test Use a.33uf ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is -2 MHz. Position the load between mm and 7 mm from the DC/DC. Lin Battery Cin Current Probe Copper Strip Scope Resistive 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.[ at 1 KHz) capacitor of a 4.7uF for the V input devices and a 2.2uF for the V and 24V devices. DC Power Source - 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.uF capacitors at the output. DC Power Source - Cin Com. Copper Strip Scope Scope Resistive DC Power Source - Com. Design & Feature Considerations Maximum Capacitive The MIR 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 27uF maximum capacitive load for dual outputs and 68uF capacitive load for single outputs. The maximum capacitance can be found in the data sheet. 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 9 C. The derating curves are determined from measurements obtained in an experimental apparatus. Position of air velocity probe and thermocouple mm / 2in Air Flow Input Source Impedance 1mm /.6in DUT 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. E-Mail sales@cdiweb.com
