Series Description
The MGDM-18 series is a full family of high performance DC/DC low profile 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 voltage choices of 3.3, 5, 12 or 15 volts. The MGDM-18 series is able to supply up to 18/20 W output power.
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 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 an excellent thermal conductive compound and packaged in a metallic case to ensure the module's integrity under high temperature conditions.
