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 reflected-ripple current is measured with a inductor Lin (4.7uH) and Cin (220uF, ESR < 1.0[ at 100 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 0-500 KHz. To Oscilloscope + + Battery +Vin Lin Cin -Vin 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. +Out DC / DC Converter Current Probe Load -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 -Vin 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 10uF for the 5V input devices, a 3.3uF for the 12V input devices and a 2.2uF for the 24V and 48V devices. + DC Power Source Copper Strip Cout Input Source Impedance Scope +Vin + DC / DC Converter Load Cin - Resistive Load +Out -Vin -Out -Out Output Ripple Reduction +Vin +Out Dual Output DC / DC Converter Com. -Vin -Out 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. Copper Strip Cout Scope Cout Scope Resistive Load + Maximum Capacitive Load 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 1000uF maximum capacitive load for dual outputs and 6800uF capacitive load for single outputs. The maximum capacitance can be found in the data sheet. - -Vin + +Vin MINMAX Cout -Vin Load -Out +Out Dual Output DC / DC Com.
