Series Description
The MGDM-35 wide input series is a full family of DC/DC power modules designed for aerospace, military and high-end industrial applications.
These modules use a high frequency fixed swiching technic at 250 KHz providing excellent reliability, low noise characteristics and high power density.
Standard models are available with wide input voltage range of 9-36, and 16-75. The serie includes single, bi and triple output voltage choices of 3.3, 5, 12, 15 volts.
No external heatsink is required for the MGDM-35 series to supply 35 W output power over the full temperature range.
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, an input undervoltage lock-out, 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 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 with a GAIA Converter automated test equipment.
