Description
This third-generation Primary-Side-Regulation (PSR)
and highly integrated PWM controller provides features
to enhance the performance of LED illumination.
The proprietary topology, TRUECURRENT™, enables
precise CC regulation and simplified circuit for LED
illumination applications. The result is lower-cost and
smaller LED lighting compared to a conventional design
or a linear transformer.
To minimize standby power consumption, the
proprietary green-mode function provides off-time
modulation to linearly decrease PWM frequency under
light-load conditions. Green mode assists the power
supply in meeting the power conservation requirements.
By using the FL103,
implemented with few
minimized cost.
LED illumination can be
