228-W converters feature 18 to 75-Vdc input

The expanded Hammerhead series, the QHHD019A0B isolated dc/dc converters, offer a 228-W output in a quarter-brick format. They provide a single regulated output voltage from an input voltage range from 18 to 75 Vdc. The converters enable input power flexibility for board designers while providing a common building block that can support multiple sockets. In terms of output voltage the converters provide a nominal 12-V output voltage that is rated for 19-A output current. The new modules achieve typical full-load efficiencies of greater than 93% at input voltages of 24 and 48 V.

Standard features of the dc/dc converters include remote on/off, remote sense, output-voltage adjustment and over-voltage, over-current and over-temperature protection. In addition, an optional heat plate is available, which allows for an external, standard, quarter-brick heat sink attachment. The modules provide a nominal output voltage of 12 V at 19-A output currents and 2,250-V isolation. Pricing begins at $31.10 each at OEM production volumes. For more information, call  888 546 3243.
