These converters operate over input voltage ranges of 4.5~5.5VDC, 10.8~13.2VDC, and 21.6~26.4VDC. This series also has single and dual output voltages of 3.3, 5, 9, 12, 15, ±5, ±12, and ±15VDC. These converters’ impressive efficiencies enable them to deliver their fully rated output power from –25°C to +75°C without a heatsink or forced-air cooling. These converters are useful for a variety of applications including distributed power systems, data communication equipment, telecommunication equipment, and industrial robot systems.

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. A 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 100KHz) capacitor of 2.2μF for the 5V input models, a 1.0μF for the 12V input models, and a 0.47μF for the 24V input models. +Vin + + DC Power Source +Out DC / DC Converter Load Cin -Vin - -Out Maximum Capacitive Load The MSLU series has a limit 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 optimal performance we recommend a maximum load of 33µF. TEST CONFIGURATIONS Input Reflected-Ripple Current Test Setup Input reflected-ripple current is measured with an inductor Lin (4.7µH) and Cin (220µF, ESR < 1.0Ω at 100KHz) 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 Cin Current Probe +Out DC / DC Converter -Vin Load -Out Peak-to-Peak Output Noise Measurement Test Use a Cout 0.33μF ceramic capacitor. Scope measurement should be made by using a BNC socket; measurement bandwidth is 0 ~ 20MHz.

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