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.
