RediSem’s Controller ICs for LLC converters demonstrate
highest performance efficiencies whilst offering extremely
low standby-powers and multiple protection features.
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’s LLC ICs
have numerous
protection features,
including:
- Capacitive Mode
protection
- Triple-mode over-
current protection
- Over-temperature
protection
- Control Loop Fault
protection
RediSem LLC LED
drivers offer the
performance of a 2-
stage converter at the
price point of a 1-stage
unit. Our LLC converters
use low-cost robust
bipolar transistors and
smaller magnetics and
EMI filtering than flyback
systems.
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.
