Santa Clara, CA and Kyoto, Japan, Oct. 08, 2024 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced new external FET-type controller ICs utilizing PWM current control mode optimized for AC-DC power supplies in various industrial applications. Mass production has begun for four variants designed to drive a wide range of power semiconductors: the BD28C55FJ-LB for low-voltage MOSFETs; BD28C54FJ-LB for medium- to high-voltage MOSFETs; BD28C57LFJ-LB for IGBTs; and BD28C57HFJ-LB for SiC MOSFETs. Although the global semiconductor shortage is beginning to ease, the supply of semiconductor components for power supplies in industrial applications continues to lag behind demand. This is particularly true for PWM controller ICs, where the limited number of manufacturers has resulted in chronic shortages, leading to numerous requests for product development. In response, ROHM has developed PWM controller ICs that address the ongoing supply issue by meeting the industrial market’s string
