02: Power Supply
Power supply units that handle larger amounts of power demand even higher effi ciency and a reduction in reactive power. ROHM offers a broad lineup that meets these needs in a variety of package types.s.
Lithium-Ion Battery Monitoring IC Series
Lithium ion batteries are increasingly being used as power storage devices. LAPIS Semiconductor offers a broad lineup that includes large capacity, high voltage, and multicell types that achieve class-leading accuracy and ultra-low power consumption.MORE
EDLC Cell Balancing IC
In the energy regeneration market the demand for EDLCs(Electric Double Layer Capacitors) is expanding for use as countermeasures against voltage sag (instantaneous voltage drop). ROHM has successfully commercialized EDLC cell balancing ICs with built-in protection functions that are compact and easy to mount.MORE
AC/DC Converter Control IC for SiC Drive
ROHM has developed AC/DC converter control ICs suitable for driving SiC MOSFETs, which are seeing increased adoption in industrial equipment. In particular, these SiC power semiconductors provide added value to the AC/DC converter market that demands fewer parts, greater energy savings, and increased miniaturization.MORE
SiC Power Devices
SiC power devices feature higher withstand voltage, lower power loss, and faster switching speeds that cannot be achieved with conventional silicon devices.
ROHM, an SiC power device pioneer, has been developing and mass producing SiC products since 2010.
ROHM offers a broad lineup of SiC power devices, from MOSFETs to SBDs and modules, designed to meet the needs of the power device market.
