Series Description
The MGDM-200 low input voltage series is a complete line of high density wide input range DC/DC power modules designed for aerospace, military and high-end industrial applications. These modules use a patented fixed switching topology at 270 KHz providing ultra wide input range, low noise characteristics and high power density. Standard models are available with ultra wide input voltage range of 9-45, 16-80 volts. The series include single output voltage choices of 3.3, 5, 12, 15, 24 volts.
The MGDM-200 low input voltage series include synchronization, load sharing, trim, current trim limitation and sense functions.
The synchronization function allows to synchronize one converter to the other or to an external frequency source. The load sharing allows parallel operation to increase output power with a true N+1 without any additionnal external components.
All modules are designed with LC network filters to minimize reflected input current ripple and output voltage ripple.
The modules have independant protection functions including input undervoltage lock-out, output overvoltage protection, output current limitation, and thermal protection. Additionnally a soft-start function reduces inrush current during start-up.
The thermal design is innovative and use baserail TM and siderail TM concept. The heat is removed through thick copper planes down to the external frame on the top and the side allowing better thermal path.
The design has been carried out with surface mount components, planar transformer and is manufactured in a fully automated process to guarantee high quality. The modules are potted with a bi-component thermally conductive compound to ensure optimum power dissipation under harsh environmental conditions.
