GE’s Critical Power business has expanded its Hammerhead series of DC/DC modules with 228W quarter-brick QHHD019A0B isolated DC/DC converters. The low-height modules provide a single, precisely regulated output voltage over an input voltage range of 18-75VDC. The modules achieve typical full-load efficiencies of greater than 93% at input voltages of 24 and 48V.

These cost-effective and energy- and space-efficient DC/DC converters enable input power flexibility for board designers while providing a common building block that can support multiple sockets. In terms of output voltage, GE’s Hammerhead converters provide a nominal 12V output voltage that is rated for 19A output current.

Standard features of GE’s QHHD019A0B DC/DC converters include remote on/off, remote sense, output voltage adjustment and over voltage, over current and over temperature protections. An optional heat plate is available, which allows for an external, standard, quarter-brick heat sink attachment - enabling designers to achieve higher output currents in high-temperature applications.

With the addition of the 228W QHHD DC/DC converters to its extensive family of Hammerhead products - which include EHHD, KHHD and SHHD modules - GE is able to provide board designers with a wide range of offerings - from 15W in a 1x1" module to 228W in a DOSA-standard, quarter brick unit. This versatility allows GE to provide board designers with the technology they need to meet their unique design challenges.
