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%.

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.
