NVE’s industry-leading
line of isolators with integrated DC-to-DC has been expanded to add versions with
3.3-to-5 volt integrated boost convertors.
Revolutionary Technology
NVE’s revolutionary IsoLoop® DC-to-DC convertor technology
and patented GMR isolation technology give these parts best-in-class performance
and miniaturization.
Boost Convertors Available
Versions are available with either 3.3-to-3.3 volt integrated DC-to-DC convertors
(IL46xx and IL761xVE) or 3.3-to-5 volt integrated boost convertors (IL48xx and
IL781xVE).
Low Parts Count
Just two external bypass capacitors are required for the DC-to-DC convertors.
No additional regulation and no ferrite beads for EMI mitigation are needed.
Fully Regulated
Some DC-to-DC convertors are only “semi-regulated,” but these parts'
supplies are fully regulated with excellent line and load regulation.
Lowest Ripple
One millivolt peak-to-peak ripple on the DC-to-DC convertor outputs is an order
of magnitude less than conventional parts and means low noise and reliable systems.
Ample Power
250 milliwatt integrated DC-to-DC convertors provide enough current for plenty
of bus nodes or external circuitry.
Soft Start
A smooth output ramp-up with a minimum two millisecond startup facilitates
power sequencing such as allowing control electronics to start before the bus
is powered.
Lowest EMI
Frequency hopping and integrated shielding provide the lowest EMI in the industry,
eliminating the need for external shielding or ferrite beads.
High Speed
The transceivers are rated at a best-in-class 40 megabits per second and
the couplers are rated at a full 110 megabits per second for speed, transmission
distance, and signal fidelity.
Full Isolation
A unique ceramic/polymer composite isolation barrier provides the industry's best
barrier resistance and virtually unlimited life. The transceivers are rated at
a full 2.5 kVrms, and the data couplers at a remarkable 4 kVrms. All
parts are UL1577 registered and certified under the stringent new VDE 0884-17
standard.
Standard Package
The parts are packaged in a JEDEC-standard 16-pin wide-body package with true
eight-millimeter creepage in accordance with IEC60601.
A Range of Configurations
Two-, three-, and four-channel versions plus half- or full-duplex RS-485 / RS-422.
Most configurations are available with either 3.3-to-3.3 volt DC-to-DC convertors
or 3.3-to-5 volt boost convertors:
Evaluation Board
An evaluation
board is available that provides a complete isolated four-channel SPI
node plus isolated power using an IL7817VE.
The four- by three-inch (100 mm by 75 mm) board provides screw terminals for connections,
plus test points for checking voltages and I/O. There are also LEDs to indicate
DC-to-DC convertor input and output power. It uses a 2s2p board with thermal vias
for optimal thermal performance.
