Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%. Ripple & Noise measurement bandwidth is 0-20 MHz. These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed. All DC/DC converters should be externally fused at the front end for protection. Other input and output voltage may be available, please contact factory.

Copper Strip -Vin -Out Copper Strip Scope Cout Cout Resistive Load Scope Design & Feature Considerations Maximum Capacitive Load The MDW1000 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. 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 on the input to insure startup. By using a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 kHz) capacitor of a 8.2uF for the 5V input devices, a 3.3uF for the 12V input devices and a 1.5uF for the 24V and 48V devices, capacitor mounted close to the power module helps ensure stability of the unit. + DC Power Source +Vin + +Out DC / DC Converter Load Cin - -Vin -Out 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 3.3uF capacitors at the output. + +Vin DC Power Source - +Out Single Output DC / DC Converter -Vin + Cout Load -Out +Vin DC Power Source - +Out Dual Output DC / DC Com. Converter -Vin -Out Cout Load Load Cout 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.
