High power converters for all standard industry input voltages

The DCM ChiP is an isolated, regulated DC-DC converter, operating from an unregulated, wide range input to generate an isolated output. With its high frequency zero voltage switching (ZVS) topology, DCMs consistently deliver high efficiency across their specified input line range. Modular DCM converters used independently or with downstream point of load (PoL) products support efficient power distribution, providing superior power system performance and connectivity from a variety of unregulated power sources to the point of load. Options include a family of DCMs with tighter output voltage regulation of±1%. The DCM VIA module provides a higher level of functionality with integrated EMI filtering, tight output voltage regulation and a secondary-referenced control interface.
