The unit operates normally once the output current is brought back into its specified range. Input Reflected-Ripple Current Test Setup Overvoltage Protection Input reflected-ripple current is measured with a inductor Lin (4.7uH) and Cin (220uF, ESR < 1.0[ at 100 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 0-500KHz. To Oscilloscope + Battery + +Vin Lin Current Probe Cin +Out DC / DC Converter -Vin Input Source Impedance Load 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. -Out Peak-to-Peak Output Noise Measurement Test Use a Cout 0.47uF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20 MHz. Position the load between 50 mm and 75 mm from the DC/DC Converter. +Vin +Out Single Output DC / DC Converter -Out +Vin +Out Dual Output DC / DC Converter Com. -Vin -Out By using a good quality low Equivalent Series Resistance (ESR < 1.0[ at 100 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. Copper Strip Cout -Vin 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. + Scope Resistive Load DC Power Source +Vin + +Out DC / DC Converter Load Cin - -Vin -Out Copper Strip Cout Scope Cout Scope Output Ripple Reduction 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 that 3.3uF capacitors are used on output. Design & Feature Considerations + Maximum Capacitive Load The MIW5000 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 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.
