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 khz) to simulated source impedance. Capacitor Cin, offsets possible battery impedance. Current ripple is measured at the input terminals of the module, measurement bandwidth is 0-0KHz. To Oscilloscope + + Lin Battery Cin Current Probe 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 0-20 MHz. Position the load between mm and 75 mm from the DC/DC. control to current control. The unit operates normally once the output current is brought back into its specified range. Overvoltage Protection The output overvoltage clamp consists of control circuitry, which is independent of the primary regulation loop, that monitors the voltage on the output terminals. The control loop of the clamp has a higher voltage set point than the primary loop. This provides a redundant voltage control that reduces the risk of output overvoltage. 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. In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor on the input to insure startup. By using a good quality low Equivalent Series Resistance (ESR < 1.0[ at khz) capacitor of a 12uF for the 12V, 4.7uF for the 24V input devices and a 2.2uF for the 48V devices, capacitor mounted close to the power module helps ensure stability of the unit. + Single Output Scope Resistive DC Power Source - + Cin Dual Output Com. Design & Feature Considerations Maximum Capacitive The MIW00 series has limitation of maximum connected capacitance on the output. The power module may operate in current limiting mode during start-up, affecting the ramp-up and the startup time. The maximum capacitance can be found in the data sheet. Overcurrent Protection Scope Resistive Scope 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 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 that 3.3uF capacitors are used on output. DC Power Source + DC Power Source - + - Single Output Dual Output Com. 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 95 C. The derating curves were determined from measurements obtained in an experimental apparatus. Position of air velocity probe and thermocouple 15mm / 0.6in mm / 2in Air Flow DUT 7
