SP6019D-Synchronous Rectifier Driver DataSheet 

DESCRIPTION 
 The fundamental of SP6019D 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. SP6019D is
specially suitable for Forward and DC/DC
Module.

FEATURES
 Offers efficiency improvement over
Schottky Diode (depends on drive
configuration of the SR).
 Drives all Power MOSFET.
 Prediction gate timing control.
 Minimum MOSFET body diode
conduction.
 Operating at high switching frequency.
 Synchronize to transformer secondary
voltage waveform.
 Linear setting of timing function.
 SOP-8 and TDFN3X3 8LC Package

APPLICATIONS
 Servers & workstations
 Storage area network power supplies
 Telecommunication converters
