SP6018
Synchronous Rectifier Driver
DESCRIPTION
The fundamental of SP6018 synchronous
rectifier (SR) driver IC is based on our U.S.
patented methods that utilize the principle of
“prediction”
logic
circuit.
The
IC
deliberatesprevious 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. Specially,
SP6018 is designed for Resonance. It also
maintains the MOSFET’s body diode conduction at
minimum level. The SP6018 is capable to adapt in
almost all existing adaptors with few adjustments
considered necessary.
