SP6018-Synchronous Rectifier Driver DataSheet 

SP6018-Application Note DataSheet 

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 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. 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 Resonance converters with few adjustments considered necessary.

FEATURES
· Offers efficiency improvement over Schottky Diode (depends on drive configuration of the SR).
