This board demonstrates an isolated, high-efficiency synchronous buck converter switch-mode
power supply (SMPS) using the world’s smallest isolators, NVE IsoLoop® MSOP Isolators.
The output is 3.3V at 750 mA.
The board has three channels of isolation to ensure the output is electrically isolated from the
input. A two-channel MSOP-8 isolator isolates synchronous rectification and a single-channel
MSOP-8 isolator isolates output-voltage feedback. MSOP isolators minimize board area.
Despite the compact components, the board has full 2.5 kV isolation and maintains 3 mm creepage.

allows the magnet to be positioned on-axis or in one of four off-axis angle sensing
zones.

This Arduino Shield board implements an H-bridge power converter using four power MOSFETs, four IL610CMTI-1E
ultrahigh CMTI isolated MOSFET drivers, and two ILDC13-15E ultraminiature isolated DC-to-DC convertors.
The board is rated for 40 volts and 50 amps, to control
up to two-kilowatt loads.
Example programs are available via our GitHub Repository.
Key features of the board are:
• A Simple three-wire Arduino interface (PWM, Dir, and Enable)
• Heat-sinking and thermal vias
• Standard Arduino Shield form factor outline
• Easy connections with large screw terminals
Specifications:
• Max. load: 2 kW (40 V / 50 A)
• Load supply line: 8 to 40 V
• Arduino input supply: 5V or 7 V to 20 V, 500 mA max.
• Logic-to-load isolation: 2.5 kV per UL 1577
• Operating Temperature Range: -40 °C to 85 °C
• Dimensions: 2.1 in. by 2.7 in. (53.4 mm by 68.6 mm)
Applications:
• Motor speed and direction control
• Robotics
• DC-to-AC invertors
The ILDC13VE is a miniature, one-quarter watt fully-regulated 3.3V-to-6V DC-DC boost convertor. The part can be used to generate isolated high-side gate supplies for H-bridges.
NVE’s proven IsoLoop® isolation technology and a unique ceramic/polymer composite barrier provide best-in-class 6 kV isolation and virtually unlimited barrier life.
The unique True-8(TM) package provides true eight-millimeter creepage in accordance with IEC60601. Maximum 5 mV peak-to-peak ripple means low noise.
The device minimizes board space and parts count, requiring just three external capacitors. No additional regulation is required and there is no minimum load.
Frequency hopping and shielding reduce EMI, and ferrite beads are not necessary for EMI mitigation.
A high-temperature process allows up to 175 °C junction temperature for full power up to 125 °C operating temperature with no derating. Integrated short-circuit protection avoids excessive power dissipation.
