Isolated Transceiver
With 3.3-to-5 V DC-to-DC Convertor |
|
|
 NVE
has introduced the IL4822
isolated RS-485/RS-422 transceiver with an integrated 3.3-to-5 volt isolated DC-to-DC
boost convertor.
It is ideal for interfacing 3.3-volt controllers to ubiquitous five-volt busses.
The new part complements the previously-announced IL4622E, which has a 3.3-to-3.3
volt DC-to-DC convertor for interfacing to newer 3.3 V busses.
The new part is based on the revolutionary IsoLoop® DC-to-DC convertor
technology first introduced in ILDC11xxx
stand-alone isolated DC-to-DC convertors.
Key IL4822 features include:
• 250 mW 3.3-to-5 volt DC-to-DC boost convertor
• 40 Mbps RS-485 or RS-422 data rate
• 1 mVp-p DC-to-DC output ripple
• 2.5 kVrms isolation
• JEDEC-standard wide-body SOIC with true 8 mm creepage
High Power
The 250 mW integrated DC-to-DC boost convertor has enough current to power a single
bus node or multiple nodes.
Highest Speed
The IL4822 is rated at a best-in-class 40 Mbps for high speed, long transmission
distances, and high signal fidelity RS-485 or RS-422 data transmission.
Lowest Ripple
One millivolt peak-to-peak ripple on the DC-to-DC convertor output is an order
of magnitude less than conventional parts and means low noise and reliable systems.
Full Isolation
Both the transceiver and DC-to-DC convertor modules are rated for full 2.5 kVrms
isolation. The parts are VDE V 0884-11 certified under the stringent new IEC 60747-17
requirements, and UL1577 registered.
Standard Package
The new part is packaged in JEDEC-standard 16-pin wide-body packages with true
8 mm creepage in accordance with IEC60601.
Lowest EMI
Frequency hopping and integrated shielding provide the lowest EMI in the industry.
Low Parts Count
The integrated DC-to-DC convertor requires no additional regulation and ferrite
beads are not necessary for EMI mitigation.
Available Now
The new IL4822E
is in stock for immediate delivery, as well as the 3.3-to-3.3 volt IL4622E
and a full line of IL76xxVE
data couplers with DC-to-DC convertors.

Happy
Mole Day |
|
|
Mole Day will be 10-23!
It's a day where we all celebrate Avogadro's Number, and a mole goes a long way
in spintronics.
For example, a mole of magnesium oxide (6.02 x 1023 molecules, or 40.3
grams) makes about an acre (43,560 square feet) of three nanometer-thick spin-dependent
tunnel barrier. |
