NVE's unique DC-to-DC convertors
have 3.3 volt inputs and are available with 3.3-, 5-, or 6-volt regulated
outputs. All versions also have a 10-volt unregulated output.
Best-in-Class Isolation
The DFN6 versions offer full 2.5 kVrms isolation, and the SOIC16 versions
have best-in-class 6 kVrms isolation and true eight-millimeter creepage under
IEC60601. Both versions are UL1577 listed and CE marked.
Ample Power
With 250 milliwatts of fully regulated power, there is plenty of current
for a range of circuitry.
Low Ripple
Less than one millivolt peak-to-peak ripple ensures low noise and reliable
systems.
Soft Start
A smooth output ramp-up with a minimum two-millisecond startup facilitates safe
power sequencing, such as allowing control electronics to start before an H-bridge
is powered.
Rugged
A maximum junction temperature of 175°C allows full-power operation up to 125°C
ambient without derating. Integrated short-circuit protection prevents excessive
power dissipation.
Minimal Parts Count
Just three simple bypass capacitors are required as external components. No additional
regulation is needed, and there is no minimum load.
Low EMC
High-frequency operation, frequency hopping, and integrated shielding ensure compliance
with FCC and CISPR 32 Class B, with no shielding or ferrite beads required.
A Better Barrier
NVE’s award-winning IsoLoop isolation technology and a unique ceramic/polymer
composite barrier provide virtually unlimited barrier life and 100 teraohm barrier
resistance.

Ultraminiature
NVE DC-to-DC convertors are available in either a SOIC16 or a 3 x 5.5 mm
DFN6, which is the world's smallest isolated DC-to-DC convertor.

 Isolated
Power Supplies with the World's Smallest DC-to-DC Convertors
NVE's unique DC-to-DC convertors
are ideal for isolated supplies for digital and analog electronics. with two of
the 3 x 5.5 mm DC-to-DC convertors.
This reference circuit provides an isolated plus/minus five-volt bipolar supply
from a single 3.3-volt supply in a small footprint with a low parts count:

|
The supplies are completely isolated, which reduces noise and provides electrical
safety.
The unregulated outputs can also be used to provide +10 and -10 volt supplies
for analog circuitry. Here is an example of an isolated triple-output supply:
Although the ten-volt outputs are unregulated, they have very low ripple. The
supply allows a 20-volt peak-to-peak amplified signal, centered around zero. Here's
a live demonstration:

West Wrap-up
Thanks to everyone who visited us at MD&M West in Anaheim, especially those
who waited in line to try our demos! Here’s a live video
of three new demos at the show.
