Input Reflected-Ripple Current Test Setup Input reflected-ripple current is measured with a inductor Lin (4.7uH) and Cin (220uF, ESR < 1.0Ω 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. +Out -Out +Vin -Vin DC / DC Converter Load Battery + Lin+ Cin To Oscilloscope Current Probe 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.

ScopeCout Copper Strip Copper Strip Design & Feature Considerations 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 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 Ω at 100 KHz) capacitor of a 15uF for the 12V input devices and a 4.7uF for the 24V and 48V devices. +Out -Out +Vin -Vin DC / DC Converter LoadDC Power Source Cin 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 to use 3.9uF capacitors at the output. +Out -Out +Vin -Vin Load DC Power Source Cout Single Output DC / DC Converter +Out -Out +Vin -Vin Load DC Power Source CoutCom. Dual Output DC / DC Converter Load Cout Maximum Capacitive Load The MKW1000 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 470uF maximum capacitive load for dual outputs and 2200uF capacitive load for single outputs. The maximum capacitance can be found in the data sheet. 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 90℃. The derating curves are determined from measurements obtained in a test setup.
