» “This study uses the ABT series sensors developed by NVE Corporation of the United States. The models are ABT375-00E and ABT600-00E, both of which are back magnetic TMR sensors... The sensor’s output signal has extremely low distortion and excellent linearity, as well as low hysteresis and a wide peak-to-peak signal range. In addition to the small size of the product, it can also be used for speed and position measurement of linear or rotary motion.”
P. -Y. Chen and P. -J. Wang, “Design and Analysis of Linear Incremental Encoder Based on Back Magnetic TMR Sensors,” 2023 Photonics & Electromagnetics Research Symposium (PIERS), Prague, Czech Republic, 2023, pp. 2142-2148.

CE Marking for NVE’s
Isolated DC-to-DC Convertors
 
NVE’s line of the world’s smallest DC-to-DC convertors is now CE marked under an EU Declaration of Conformity including general safety, electromagnetic compatibility (EMC), and RoHS.

General safety
ILDC-Series DC-to-DC convertors have a unique ceramic/polymer composite isolation barrier, providing the industry’s best barrier resistance and virtually unlimited life. The ultraminiature DFN6 versions are rated at a full 2.5 kVrms, and the SOIC16W versions are rated at a remarkable 4 kVrms. All parts are UL1577 registered and tested under the stringent new VDE 0884-17 standard.

EMC
The parts meet the stringent CISPR32 Class B (FCC Class B/ EN 55032:2017/A11:2020) standards for radiated emissions without any additional external components. Unlike conventional parts that require ferrite beads, inductors, or large capacitors, NVE’s DC-to-DC convertors only require a small overlapping stitching capacitance on inner PCB layers. Check out the revised datasheet and a new application bulletin for details on getting your designs to pass EMC testing the first time, every time.
 
RoHS
NVE’s ILDC-Series, like all NVE part numbers, are offered with a RoHS-compliant package (“E” suffix). Need a Pb-Sn package (no “E” suffix) for non-RoHS applications? NVE offers leaded parts too!

Ultraminiature
The 3 x 5.5 mm DFN6 is the world’s smallest isolated DC-to-DC convertor. JEDEC-standard SOIC16 package versions are also available with true eight-millimeter creepage and 4 kV isolation.

Minimal Parts Count
Three simple bypass capacitors are the only external parts required. No additional regulation is needed and there is no minimum load.
 
Ample Power
250 milliwatts of fully-regulated power means plenty of current for an isolated RS-485 bus or high-side MOSFET drivers.
 
Low Ripple
Less than one millivolt peak-to-peak ripple means low noise and reliable systems.

Soft Start
A smooth output ramp-up with a minimum two millisecond startup facilitates power sequencing such as allowing control electronics to start before an H-bridge is powered.

Rugged
A 175 C maximum junction temperature allows full power up to 125 C ambient with no derating. Integrated short-circuit protection prevents excessive power dissipation.
 
Versatile Applications
ILDC1x parts are ideal for a number of applications, including:
  • Ground-loop mitigation
  • RS-485 / RS-422 bus supplies
  • Isolated SPI / Microwire interfaces
  • Isolated ADC and DAC power supplies
  • “2 x MOPP” medical systems requiring true 8 mm creepage
 
Evaluation Boards
ILDC1x-Series evaluation boards have everything you need, which is just the part and three bypass capacitors. There are also LEDs to show the convertor is operating, and screw terminals for easy connections. No ferrite beads or external regulators are necessary.

Immediate Delivery
ILDC-Series parts and evaluation boards are in stock for immediate delivery.
