SP6003
Synchronous Rectifier Driver
DESCRIPTION
The fundamental of SP6003 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 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. It also
maintains the MOSFET’s body diode conduction
at minimum level. The SP6003 is capable to
adapt in almost all existing flyback converters
with few adjustments considered necessary.
APPLICATIONS
Servers & workstations
Storage area network power supplies
Telecommunication converters
Embedded systems
Industrial & commercial systems using high
current processors
FEATURES
Offers efficiency improvement over Schottky
Diode (depends on drive configuration of the
SR).
PIN CONFIGURATION (SOP-8)
Drives all logic level Power MOSFET.
Prediction gate timing control.
Minimum MOSFET body diode conduction.
Operating frequency up to 350 KHz.
Synchronize to transformer secondary PART MARKING
voltage waveform.
