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 crossconduction at the same time. Specially, SP6015
is designed for LLC applications, and variable
switching frequency system .

APPLICATIONS
 Storage area network power supplies
 Telecommunication converters
 Embedded systems
 Industrial & commercial systems using high
current processors
 Power converters to meet Lot 6 requirement
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
 Offers efficiency improvement over Schottky
Diode.
 Low Standby Power to meet DOE Lot 6
Requirement .
 Dual gate driver for N-channel MOSFET
 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.
