Synchronous Rectifier Driver
DESCRIPTION
APPLICATIONS
The fundamental of SP6012 synchronous rectifier Servers & workstations
(SR) driver IC is based on our U.S. patented methods that utilize the principle of “prediction”
Storage area network power supplies
logic circuit. The IC deliberates previous cycle timing to control the SR in present cycle by “predictive” algorithm that makes adjustments to

time. It also maintains the MOSFET’s body diode
conduction at minimum level. The SP6012 is
capable to adapt in almost all existing forward
converters with few adjustments considered
necessary.
FEATURES Offers 4 to 8% efficiency improvement over
Schottky Diodes (depend on drive configuration of the SR).
PIN CONFIGURATION (SOP-10)
Drives all level Power MOSFET.
Prediction gate timing control.
Minimum MOSFET body diode conduction.
Operating frequency up to 650 KHz.
Synchronize to transformer secondary voltage waveform.
