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 + Lin Current Probe +Vin +Out Load 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 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. 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 4.7uF for the 24V input devices and a 2.2uF for the 48V devices. + DC Power Source + Cin -Vin -Out +Vin DC / DC Converter +Out Load DC / DC Converter -Vin -Out Cin 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.

Copper Strip Cout Cout Scope Resistive Load Scope -Out Cout Load Design & Feature Considerations Maximum Capacitive Load The MIW2300 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 680uF maximum capacitive load for 3.3V output, 470uF for 5V output, 330uF for 12V output, 220uF for 15V output, 150uF for {12V output and 100uF for {15V output.

To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 90 C.
