NEW! Best-in-Class Isolators
with DC-to-DC Convertors
IL4622 / IL4822
IL4622 / IL4822
NVE’s industry leading isolators with integrated DC-to-DC converters have always had the smallest packages plus best-in-class regulation and ripple. Now they are even more feature-rich with soft start.

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.

Soft Start
The new parts feature a smooth output ramp-up with a minimum two millisecond startup to facilitate power sequencing such as allowing control electronics to start before the bus is powered.

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.

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.

Boost Convertors Available
Versions are available with either 3.3-to-3.3 volt integrated DC-to-DC convertors or 3.3-to-5 volt
integrated boost convertors.

Adequate Power
250 milliwatt integrated DC-to-DC convertors provide enough current for plenty of bus nodes or external circuitry.

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
Various two-, three-, and four-channel data couplers are available for a variety of applications. The transceivers are available as half- or full-duplex with either a 3.3-to-3.3 volt DC-to-DC convertor or 3.3-to-5 volt boost convertor for five-volt RS-485 or RS-422 busses.
