    Using the LTM2881 as an Isolated 5V Power Supply
    The LTM2881 is an isolated RS485 transceiver that guards against large ground-to-ground differentials. An onboard DC/DC converter provides isolated 5V power to the output. This application note shows the LTM2881 configured as a dedicated isolated power supply with the RS485 transceiver disabled, providing a simple powerful general purpose isolated power supply capable of delivering 1W at 5V.

    Using the LTM2881 as an Isolated 5V Power Supply
    Brian Jadus
    Features: 2500VRMS Isolated 5V 1W Power With No External
    Components n В® The LTM 2881 is an isolated RS485 transceiver that guards
    against large ground-to-ground differentials. An onboard
    DC/DC converter provides isolated 5V power to the output.
    Figure 1 shows the LTM2881 configured as a dedicated
    isolated power supply with the RS485 transceiver disabled,
    providing a simple powerful general purpose isolated power
    supply capable of delivering 1W at 5V. Figure 2 shows a
    logically-controlled switched output by taking advantage of
    the isolated RS485 driver to control a discrete PMOSFET.
    The controlling signal DI operates relative to the VL supply, which supports voltages from 1.62V to 5.5V. In both
    configurations, observation of a VCC2 fault is accomplished
    by observing a high impedance condition on RO or DOUT .
    When VCC2 is greater than 2.6V, RO and DOUT are driven
    to the appropriate logic level based on the inputs A and
    B and DIN. When VCC2 is less than 2.4V, RO and DOUT are
    high impedance. n 5V (LTM2881-5) or 3.3V (LTM2881-3) Input Supply

    Isolated Data Transmission and Power Conversion
    Integrated Into a Surface Mount Package
    Keith Bennett Galvanic isolation is used in a variety of industries, most commonly to provide safety
    against potentially lethal voltages. Isolation is also used to eliminate the effects of noise
    and common mode voltage differences created by ground loops, or as a level shifter
    between dissimilar operating voltages. Typically, building an isolated system requires
    a number of passive and active components on either side of the isolation barrier, in
    addition to the barrier components themselves. These barrier components can be
    optical, magnetic, capacitive, RF or even GMR (giant magnetoresistance) devices.
    Barrier components are notoriously difficult to use, adding significant design
    time and cost to isolated systems. With
    this in mind, Linear Technology has
    developed a line of ВµModuleВ® isolators that reduces the design of isolated
    systems to simply plugging in a module—no complex barrier components
    are required. In fact, ВµModule isolators
    require no external components at all.
    Linear Technology ВµModule isolators
    use magnetically coupled techniques to
    provide data and power isolation in a
    single package. The result is an easy-touse, low power, robust solution with
    excellent field immunity. The LTM2881
    isolated RS485/RS422 transceiver and LTM2882 dual isolated RS232 transceivers use ВµModule isolator technology
    to provide complete transceiver-pluspower solutions in 15mm Г— 11.25mm ...
