SP6014 Synchronous Rectifier Driver DESCRIPTION The fundamental of SP6014 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 linear 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 crossconduction at the same time. Specially, SP6014 is designed for LLC applications, and.

SP6014 Synchronous Rectifier Driver DESCRIPTION The fundamental of SP6014 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 linear 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 crossconduction at the same time. Specially, SP6014 is designed for LLC applications, and variable switching frequency system . APPLICATIONS  Switching Mode Power Supply (CCM&DCM&QR) for Flyback , Forward or LLC Applications  Storage area network power supplies  Telecommunication converters  Embedded systems  Industrial & commercial systems using high current processors  Power converters to meet Lot 6 requirement FEATURES  Offers efficiency improvement over Schottky Diode.  Low Standby Power to meet DOE Lot 6 Requirement .  Drives all level Power MOSFET.  Prediction gate timing control.  Minimum MOSFET body diode conduction.  Operating frequency up to 250 KHz.  Synchronize to transformer secondary voltage waveform.  Self detect DCM / CCM to enhance the performance under the variable switching frequency condition.
