extreme widetrim windows from 10% to 110% of the nominaloutput voltage.The main power transformer designed for more than150W power is a multi-layer planar transformer which allows 100% reproductibility for optized module efficiencies.The controlled feedback regulation is located at thesecondary side allowing a high regulation bandwidth and a very fast response to load changes. > The MGDM-150 high input series DC/DC converter isbased on a constant 210KHz pulse-width modulatedforward topology designed for ultra large inputrange .The output voltage is monitored on the secondaryside avoiding the use...

12-1 Input Undervoltage Lockout > 12-1-1 Undervoltage Lockout (UVLO) An undervoltage protection is implemented to lock off theconverter as long as the input voltage has not reached the UVLO turn-on threshold (see section 4 for value) which is the minimum input voltage required to operate without damaging the converter. UVLOTurn-on Turn-off UVLO VinOnOff 12-2 Output Over Current Protection (OCP) > The MGDM-150 low input series incorporates a foldback currentlimit and protection circuit. When the output current reaches 115% of its full-rated current (Icurrent limit), the output vol- tage falls and...
