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 0-20MHz. 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. To order the converter with Remote On/Off function, add suffix RC (e.g. MKW2621-RC) to order code. To order the converter with input filter meeting EN55022 Class A , add suffix A (e.g. MKW2621A) to order code. To order the converter with heatsink, please add suffix H (e.g. MKW2621H) to order code. That “natural convection” is about 20LFM but is not equal to still air (0 LFM). Specifications are subject to change without notice.

MKW2600 SERIES ® DC/DC CONVERTER 15W Test Setup Input Reflected-Ripple Current Test Setup Input reflected-ripple current is measured with a inductor Lin (4.7µH) and Cin (220µF, 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. To Oscilloscope + + Battery +Vin Lin DC / DC Converter Current Probe Cin +Out -Vin Load -Out Peak-to-Peak Output Noise Measurement Test Use a Cout 0.47µF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20 MHz.

Copper Strip -Vin -Out Scope Cout Resistive Load Cout Scope Copper Strip Technical Notes 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 -Vin terminal. The switch can be an open collector or equivalent. A logic low is -0.7V to 0.8V. A logic high is 2.5V to 5.5V. The maximum sink current at on/off terminal during a logic low is -1 mA. The maximum allowable leakage current of the switch at on/off terminal (2.5 to 5.5V) is 50µA. 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 < 1.0Ω at 100 KHz) capacitor of a 22µF for the 12V input devices and a 6.8µF for the 24V and 48V devices. + 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 4.7µF 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 Maximum Capacitive Load The MKW2600 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 220µF maximum capacitive load for dual outputs and 470µF 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 100℃. The derating curves are determined from measurements obtained in a test setup.
