RediSem’s extensive experience in IC design and power management delivers differentiated power management ICs that are simply more efficient and environmentally friendly. A high level of integration reduces component count and cost, while reliability is ensured by design. All our power management IC products are supported by turn-key example designs enabling rapid product development for our customers. Our IC products are qualified and used by the world’s top tier lighting and power supply manufacturers to achieve product performance not available with standard products. RediSem products have significant compelling advantages over those of its competitors: • Unique Resonant BJT Converter Topology • Efficient, simple and low EMI solutions • Complete system design – not just ICs • Complete range of ICs available for lighting and SMPS
