5 DC/DC W MINMAX MKW00 Series Test Configurations Input ReflectedRipple Test Setup Input reflectedripple current is measured with a inductor Lin (.7uH) and Cin (0uF, ESR <.0Ω at KHz) to simulate source impedance. Capacitor Cin, offsets possible battery impedance. ripple is measured at the input terminals of the module, measurement bandwidth is 000 KHz. To Oscilloscope Battery Lin Probe Cin PeaktoPeak Output Noise Measurement Test Use a 0.7uF ceramic capacitor. measurement should be made by using a BNC socket, measurement bandwidth is 00 MHz. Position the load between 0 mm and 7 mm from the DC/DC. Resistive Com. Resistive Design & Feature Considerations Remote On/Off Positive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin, and off during a logic low. To turn the power module on and off, the user must supply a switch to control the voltage between the on/off terminal and the terminal. The switch can be an open collector or equivalent. A logic low is V to 0.8V. A logic high is.v to.v. The maximum sink current at on/off terminal during a logic low is. The maximum allowable leakage current of the switch at on/off terminal (. to.v) is 0uA. 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 currentlimit 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 Impedance The power module should be connected to a low acimpedance 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 <.0Ω at KHz) capacitor of a uf for the V input devices and a.8uf for the V and 8V devices. 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.7uf capacitors at the output. Com. Maximum Capacitive The MKW00 series has limitation of maximum connected capacitance at the output. The power module may be operated in current limiting mode during startup, affecting the rampup and the startup time. For optimum performance we recommend 0uF maximum capacitive load for dual outputs and uf 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. The derating curves are determined from measurements obtained in a test setup. Position of air velocity probe and thermocouple 0mm / in mm / 0.in Air Flow DUT 0/09/7 REV Page of
