Redisem Limited

RediSem develops and sells ICs for energy-efficient AC/DC power supply and LED lighting applications. RediSem's unique patented Controlled Self Oscillating Converter (CSOC) topology allows for high levels of integration and control for single-stage LLC converters with low-cost, robust bipolar transistors.

For LED driver applications, RediSem offers controller ICs designed for single-stage LLC converters with integrated Power Factor Correction (PFC). This single-stage LED driver solution eliminates flicker issues commonly associated with conventional single-stage systems, providing significantly higher efficiency and smaller sizes. RediSem's controller ICs for LED drivers feature advanced Primary Side Regulation (PSR) control for LLC converters with bipolar transistors for powers from 1-200W.

For AC/DC power supply applications, RediSem has a range of controller ICs that enable LLC converters at previously unattainable price/performance levels. Key benefits for AC/DC power supply applications include high efficiency, very low Electromagnetic Interference (EMI) and an attractive cost/performance ratio. A range of IC products is available for applications like AC/DC adapters and embedded power supplies.
