World’s
Smallest DC-DC Convertor |
|
|
 |
| ILDC11-15E
Ultraminiature Isolated DC-DC Convertor |
NVE is launching the world’s
smallest isolated DC-DC convertor, based on its revolutionary IsoLoop isolation
technology.
Now you can eliminate ground loops and get the noise reduction and safety of isolated
power in a package no bigger than an op-amp.
A (REALLY) Small Part
The ILDC11-15E
provides one-quarter watt of regulated, fully-isolated power with a 3.3 volt
input and output in a 3 x 5.5 x 0.9 mm DFN package. The 0.015 cm³
package is the equivalent of 1/8000th brick, and provides an energy density of
17 W/cm³.

Minimal Parts Count
Three inexpensive bypass capacitors are the only external parts required. No additional
regulation is needed and there is no minimum load. Frequency hopping and shielding
quash EMI and make ferrite beads unnecessary.
Big Features
The ILDC11-15E generates a minimum of 80 mA of output current.
NVE’s patented IsoLoop
technology uses a unique ceramic/polymer composite barrier for full 2.5 kV
isolation and virtually unlimited barrier life.
A 175 °C maximum junction temperature allows full power up to 125 °C
ambient temperature with no derating. Integrated short-circuit protection prevents
excessive power dissipation.
Evaluation Board
The ILDC11
evaluation board has an ILDC11-15E plus the three required external
bypass capacitors as well as LEDs to show the device is operating. Screw terminals
provide easy connections.
RS-485 Demonstration Boards
The ILDC11 is ideal for generating isolated bus supplies for RS-485 nodes. Two
different boards demonstrate isolated RS-485 nodes.
A 3.3-volt
node uses an ILDC11-15E DC-DC convertor and a IL3685PE
3.3-volt isolated transceiver. The 5-volt
node uses an IL2985E
low-power 5-volt transceiver, an ILDC11-15E, and a commodity boost regulator.
These 4 x 3 inch (100 x 75 mm) boards provide screw terminal and test point connections.
Immediate Delivery
The ILDC11-01 and demonstration boards are in stock
for immediate delivery.
Coming Soon: Versions With Integrated Transceivers
Watch this space for the launch of isolated RS-485 and RS-422 transceivers with
integrated DC-DC convertors. The new devices will provide best-in-class performance
while minimizing board space and parts count.
