Synchronous Rectifier Driver
The fundamental of SP6003 synchronous
rectifier (SR) driver IC is based on our U.S.
patented methods that utilize the principle of
“prediction” logic circuit. The IC deliberates
previous cycle timing to control the SR in
present cycle by “predictive” algorithm that
makes adjustments to the turn-off time, in order
to achieve maximum efficiency and avoid
cross-conduction at the same time. It also
maintains the MOSFET’s body diode conduction
at minimum level. The SP6003 is capable to
adapt in almost all existing flyback converters
with few adjustments considered necessary.
