Description
The FLS-XS series of general lighting power controllers
includes highly integrated power switches for medium- to
high-power lumens applications. Offering everything
necessary to build a reliable and robust half-bridge
resonant converter, the FLS-XS series simplifies designs
and improves productivity, while improving performance.
The FLS-XS series combines power MOSFETs with fast-
recovery type body diodes, a high-side gate-drive circuit,
an accurate current controlled oscillator, frequency limit
circuit, soft-start, and built-in protection functions. The
high-side gate-drive circuit has common-mode noise
cancellation capability, which guarantees stable
operation with excellent noise immunity. The fast-
recovery body diode of the MOSFETs improves reliability
against abnormal operation conditions, while minimizing
the effect of reverse recovery. Using zero voltage
switching (ZVS) dramatically reduces the switching
losses and significantly improves efficiency. ZVS also
reduces switching noise noticeably, which allows a small-
sized Electromagnetic Interference (EMI) filter.
The FLS-XS series can be applied to resonant converter
topologies such as series resonant, parallel resonant,
and LLC resonant converters.
