SP6015-Synchronous Rectifier Driver  DataSheet
DESCRIPTION
The fundamental of SP6015 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 cross-conduction at the same time. Specially, SP6015 is designed for LLC applications, and variable switching frequency system .
The SP6015 is a dual fast turn-off intelligent
controller to drive two N-CH power MOSFETs
in LLC resonant converters for synchronous
rectification.
FEATURES l Offers efficiency improvement over Schottky Diode.
l Low Standby Power to meet DOE Lot 6 Requirement .
l Dual gate driver for N-channel MOSFET
l Drives all level Power MOSFET.
l Prediction gate timing control.
l Minimum MOSFET body diode conduction.
l Operating frequency up to 250 KHz.
l Synchronize to transformer secondary voltage waveform.
l Self detect DCM / CCM to enhance the performance under the variable switching frequency condition.
APPLICATIONS
l Storage area network power supplies
l Telecommunication converters
l Embedded systems
l Industrial & commercial systems using high current processors
l Power converters to meet Lot 6 requirement
