SP6019
Synchronous Rectifier Driver
DESCRIPTION
The fundamental of SP6019 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. Specially,
SP6019 is designed for Forward .
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 Power MOSFET.
• Prediction gate timing control.
• Minimum MOSFET body diode conduction.
• Operating frequency up to 400 KHz.
• Synchronize to transformer secondary _{PART MARKING}
voltage waveform.
