ROHM has announced a system power supply IC for the car audio market that, according to the company, features the lowest power consumption in the industry. The BD49101AEFS-M leverages ROHM’s expertise in car audio power system design to achieve an optimised system based on a high-efficiency DC/DC converter, reducing power consumption by 65%, from 13.3W with ROHM’s conventional products to an industry-leading 4.66W.

Two Power Management Integrated Circuits (PMICs) have been released for mass production by ROHM. These PMICs are optimised for low power and will enable fanless designs of space conscious mobile PC products such as Ultrabooks, 2-in-1 detachables and tablets built around Intel’s 14nm Skylake processor.

  ROHM has announced the availability of high accuracy single-rank 1608-size high-brightness chip LEDs optimised for applications such as industrial equipment, consumer devices and automotive systems.

ROHM has announced the development of a 1200V/300A full SiC power module designed for inverters and converters in solar power conditioners and industrial equipment. The 300A rated current makes the BSM300D12P2E001 suitable for high power applications such as large-capacity power supplies for industrial equipment.

The SPS IPC Drives show recently saw ROHM introduce its new 12 to 76V input, 3A variable output voltage, DC/DC Buck converter with an integrated 76V MOSFET optimised for high power (high voltage x large current) applications such as motors, factory automation equipment, communications infrastructure, and industrial machinery.

A new class of power receiver controller ICs compatible with the latest USB Power Delivery (Rev2.0) and Type-C (Rev1.1) standards and has recently been announced by ROHM. The BM92TxxMWV series supports not only conventional USB power supply up to 7.5W, but the newly expanded power range as well up to 100W (20V/5A) for USB Type-C connected devices. 

ROHM’s recently announced AC/DC converter control IC, designed specifically for SiC MOSFETs in industrial equipment such as servers and other large power applications, was showcased at SPS IPC Drives. The BD7682FJ-LB allows the easy implementation of SiC-MOSFETs to an AC/DC converter which has proved challenging when using discrete configurations due to the large number of components required. 

The SPS IPC Drives show in Nuremberg saw ROHM launch its IPM (Intelligent Power Module) family optimised for high speed and power efficient operation in motor driving. The 600V modules integrate a range of components such as gate drivers, bootstrap diodes, IGBTs or ROHM’s proprietary Low Ron SuperJunction Power MOSFETs (PrestoMOS) as well as a fly wheel diode (FWD) within a single compact package.

ROHM has received certification from WPC (Wireless Power Consortium) for its reference design using the BD57020MWV wireless power transmitter IC. This is the first device in the world certified to be compliant with the Qi medium power specification.

ROHM has announced a transceiver IC compatible with the low-speed, low-cost CXPI communication protocol for use in body control applications, including steering switch, AC and instrument panel systems. The BD41000FJ-C enables multiplexing between ECUs, contributing to decreased vehicle weight and improved fuel efficiency by reducing the number and size of wiring harnesses.

  ROHM has announced a 12 to 76V input, 3A variable output voltage, DC/DC Buck converter with integrated 76V MOSFET optimised for high power applications such as motors, factory automation equipment, communications infrastructure, and industrial machinery.  

At SPS IPC Drives, 24th to 26th November, Nuremberg, ROHM will present its latest power modules for high-reliable, high-speed switching as well as SiC MOSFET driving (Hall 1 - Booth 320). All devices offer not only optimised power management features, but also innovative and compact package designs tailored to the needs of a wide range of applications, e.g. large power supplies, inverters, industrial equipment and servers.
