Test Configurations Input Reflected-Ripple Current Test Setup Input reflected-ripple current is measured with a inductor Lin (4.7uH) and Cin (2uF, ESR < 1.0[ at 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 0-0 KHz. Overcurrent Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. The unit operates normally once the output current is brought back into its specified range. Input Source Impedance To Oscilloscope + + Lin Battery Cin Current Probe 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. 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. Peak-to-Peak Output Noise Measurement Test Use a 0.47uF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0- MHz. Position the load between mm and 7 mm from the DC/DC. Copper Strip Scope Resistive 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 KHz) capacitor of a 10uF for the V input devices, a 3.3uF for the V input devices and a 2.2uF for the 24V and 48V devices. + DC Power Source - + Cin Output Ripple Reduction Com. Copper Strip Scope Scope Resistive 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 3.3uF capacitors at the output. + Design & Feature Considerations Maximum Capacitive DC Power Source - The MIW3000 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 0uF maximum capacitive load for dual outputs and 60uF capacitive load for single outputs. The maximum capacitance can be found in the data sheet. + DC Power Source - Com. REV:0 0/04 6
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 C. The derating curves are determined from measurements obtained in an experimental apparatus. Position of air velocity probe and thermocouple 1mm / 0.6in mm / 2in Air Flow DUT 7 REV:0 0/04
