1-General
The MGDI-10 series is a full family of DC/DC power modules designed for use in distributed power architecture and are particularly suitable for mobile or ground fixed applications in transportation, industry and telecommunication areas. These modules use a high frequency fixed switching technic at 500 KHz providing excellent reliability, low noise characteristics, high power density and a low profile package. Standard models are available with nominal input voltages as 5, 12, or 24 volts in range of 4,5-5,5, 9-18 or 18-36 volts. The series include single and bi output voltage choices of 3,3, 5, 12, 15, +/-5, +/-12 or +/-15 volts. No external heatsink is required for the MGDI10 series to supply 10W output power over the case temperature range of -40C up to 95C. The MGDI-10 series is designed in conformity with safety standards EN60950 and UL1950. All the modules are designed with LC network filters to minimize reflected input current ripple and output voltage ripple according to EN55022 and FCC Part 15J standard. The modules include a soft-start, and a permanent short circuit protection to ensure efficient module protection. The soft-start allows current limitation and eliminates inrush current during start-up. The short circuit protection completely protects the modules against short-circuits of any duration by a shut-down and restores to normal when the overload is removed. The design has been carried out with surface mount components and is manufactured in a fully automated process to guarantee high quality. Each module is tested and burned in with a GAIA converter automated test equipment.

Note * : For proper operation the MGDI-10 module requires to install a 22F chemical or tantalum capacitance accross output terminals. Note ** : The ripple output voltage is the periodic AC component imposed on the output voltage, an aperiodic and random component (noise) has also to be considered. This noise can be reduced by adding an external capacitance (typically 10nF/rated voltage depending on isolation requirement) connected between the pin Gin and the pin Gout of the converter. This capacitance should be layed-out as close as possible from the converter.

MGDI-10 Standard Input Series 9- Application Notes
9-1 Short Circuit Protection
Industrial Grade
The short circuit protection device protects the modules against short circuits of any duration and restores the module to normal operation when the short circuit is removed. 9-2 Custom Output Any of the bi output converters can be configured to produce output of 10V (+/-5 output models), 24V (+/-12V output models), or 30V (+/-15V output models) by connecting the load across the output (+) and the output (-) with either output grounded, and leaving the common pin floating. 9-3 Safety The MGDI-10 series is recognized according to UL1950, EN60950 and EN41003. The isolation voltage is an operational insulation in accordance with EN60950 and the DC/DC module shall be installed in an end-use equipement. 9-4 Ambient versus Case Temperature The MGDI-10 series operating case temperature at full load must not exceed 95C. The maximum ambient temperature admissible for the DC/DC converter corresponding to the maximum operating case temperature depends on the ambient airflow, the unit mounting/orientation, the cooling features and the power dissipated. Thermal calculation shows two areas of operation : * a normal operation area in a free natural ambient convection (grey area in the following graph), * an area with cooling features (air flow or heatsink ) ensuring a maximum case temperature below 95C at full load (white area in the following graph).
