March 09, 2017 by Power Pulse1595211359

ROHM Group at APEC 2017 will showcase their latest power technologies and solutions for the industrial, automotive, personal transportation, IoT, and consumer fields. Demos highlighting key products will also be shown. Highlighted products will include:

Nano-Pulse Control Buck DC/DC Converter ROHM's latest dc-dc converter utilizes proprietary technology to reduce the minimum ON time to an unprecedented 20ns – 6x shorter than existing solutions – enabling step-down operation from high input voltages, including 48V used in the automotive and industrial sectors, to 3.3V at a constant frequency of 2MHz. In addition, current-mode control provides easy phase compensation using fewer external parts, while the integrated high-voltage MOSFET expands the input voltage range to 65V for broader applicability.

Silicon-Carbide IPM ROHM's new SiC MOSFET IPM, which is expected to contribute to greater energy savings in home appliances and small industrial equipment, features: (1) reduced switching (Eon) and conduction losses vs IGBT and silicon MOSFET IPMs, (2) 77% and 50% lower power loss at lower inverter currents compared with IGBT and Si MOSFET IPMs, respectively, and (3) equivalent power loss at 30kHz vs of IGBT IPMs at 5kHz. In addition, a new gate driver IC is integrated that reduces turn ON and recovery losses over conventional solutions.

Nano-Energy DC-DC Converter This latest ultra-low-power buck dc-dc converter features a current consumption of only 180nA, the lowest in the world. Additional benefits include 9 selectable output voltages and minimal dropout with 100% duty cycle, making it ideal for everything from portable devices to sensor/security systems and other low-power applications.

Highlighted demos will include: SiC Technology for Formula E Inverters Motor sports Formula E, the world's premiere racing class for electric vehicles, is garnering interest as a platform for further innovation in the electric car sector. Last year ROHM became an official technology partner of Formula E team Venturi, providing SiC power devices for inverters that comprise the core of the drive system in electric race cars.

EcoReco Scooter EcoReco's Model R scooter represents an innovative new take on the personal electric vehicle by leveraging power devices along with smart sensors and wireless connectivity to deliver unprecedented performance, comfort, and convenience. Integrated are ROHM's buck converters, LDOs, and power MOSFETs, together with ambient/proximity sensors, EEPROMs, and Kionix's 6-axis accel-gyro sensor.

Toasting with SiCs SiC makes operation at high temperatures possible. The inherent characteristics of wide bandwidth, high breakdown electric field, and high thermal conductivity make high temperature operation possible with no performance degradation. This demo will show the stable switching characteristics of SiC even at high temperatures.

Industry session presentations will include: “Gate Driver Selection,” Mitch Van Ochten, Location: Room 2, Date/Time: Thursday, March 30 – 8:30AM

“SiC Trench MOSFETs and Intelligent Power Modules (IPMs),” Kengo Ohmori, Location: Room 1, Date/Time: Thursday, March 30 – 2:00-5:25PM.
