Series Description
The MGDM-04 series is a full family of high performance and low profile DC/DC power modules designed for aerospace, military and high-end industrial applications. These modules use a high frequency fixed switching technic at 480 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 28 volts in range of 4.5-5.5 , 9-36 or 16-40 volts. The series include single, bi and triple output voltage choices of 3.3, 5, 12, 15, +/-5, +/-12 or +/-15 volts. No external heatsink is required for the MGDM-04 series to supply 4W output power over the case temperature range of -40°C up to 105°C.
All the modules are designed with LC network filters to minimize reflected input current ripple and output voltage ripple.
The modules include a soft-start, a permanent short circuit protection and an output overvoltage protection to ensure efficient module protections.
The soft-start allows current limitation and eliminates inrush current during start-up. The short circuit protection completely protects the module 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 before and after encapsulation. The modules are potted with a bi-component thermal conductive compound and packaged in a metallic case to ensure the module’s integrity under high environmental conditions.
