pSemiTM Corporation (formerly Peregrine Semiconductor), a Murata company focused on semiconductor integration, introduces the PE23300, the industry’s only fully integrated LED boost power supply in package (PSiP) based on a charge-pump, switched-capacitor architecture that offloads most of the power-conversion work from the inductor to capacitors in the charge pump. Powering up to eight LED strings at […]

High-speed GaN FET driver switches at 40 MHz
Audio systems are challenged to both minimize size and deliver exceptional audio quality to listeners. At the system-design level, better audio performance and sound quality occur when distortion is reduced. MOSFET components have parasitic diodes and gate capacitance that creates jitter and distortion in class-D audio systems, whereas GaN FETs have much smaller gate capacitance […]
LED driver ICs offer 1W of power savings in LED boost circuit
Peregrine Semiconductor Corp., a Murata company, announces Arctic Sand’s new product family—the ARC3C family of LED driver ICs. The ARC3C product line targets the fast growing, ultra-high-definition (UHD) LCD displays market for notebook computers, Ultrabooks and 2-in-1 convertibles. The products deliver dramatic improvements in power conversion efficiency, while achieving the lowest “z” height profile and smallest […]
