Linear Technology Corporation introduces the LTC4224, a compact, low voltage Hot Swap controller for protecting boards and backplanes that use two 1V to 6V voltage supplies. Systems, including fiber optic networks, will benefit from the simplified control with independent turn-on and adjustable ramp of the two supplies. In recent years, multisource agreements like XENPAK have defined fiber optic transceiver modules that provide transmission rates up to 10Gbits/sec over distances as long as 80km. Since then, more versatile definitions like X2 or Xpak have emphasized smaller form factors for space-constrained applications. |

MILPITAS, CA February 12, 2008 Linear Technology Corporation introduces the LTC4218 Hot Swap Controller for protecting boards with load supply voltages ranging from 2.9V to 26.5V. When a board is plugged into a backplane, large inrush currents can create a glitch on the load supply causing other boards on the bus to malfunction. The LTC4218 enables safe board insertion and removal from a live backplane, using an external N-channel pass MOSFET in the power path to limit the inrush current during power up. |
