RediSem’s ICs for fluorescent lighting add high performance, control and protection to the conventional self-oscillating bipolar transistor circuits used in many ballasts and CFLs.
Our Fluorescent Lighting IC Products
       RediSem LLC  drivers have higher efficiency than flyback converters. Resonant converter operation minimizes losses resulting in lower component temperatures and smaller cases. All our designs have efficiencies exceeding 90%.
High Efficiency
Extensive Control
Long Lamp Life
Simple Design
       RediSem ICs 2101 and 2201 have sophisticated in-built control mechanisms, including: -  Controlled preheat current - Controlled ignition ramp - Lamp power limit at high mains - Capacitive mode detection - Automatic dead-time control
       RediSem’s fluorescent ICs dramatically improve lamp life to over 30,000 lamp starts whilst offering efficient reliable operation over a wide range of mains voltages and temperatures. Ballasts are fully protected and shut down safely at the lamp’s End- of-Life (EOL)
       RediSem has complete application designs and demonstrator units available for all its ICs. These production-ready LLC driver designs come with full design infopacks and can be easily customized and optimized.
