SP6052-High Frequency Synchronous Rectifier Driver


SP6052-High Frequency Synchronous Rectifier Driver DataSheet 

DESCRIPTION
    The fundamental of SP6052 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.
    SP6052 is especially 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 500Khz.
 Synchronize to transformer secondary voltage waveform.
 Linear setting of timing function.
 Minimum VDS pulse masking function
 Bi-directional rapid load protection function.
 Self-detecting DCM / CCM to enhance the performance under the variable switching frequency condition.
 SOP-8 Package

APPLICATIONS
 Storage area network power supplies
 Servers & workstations
 Embedded systems
 Industrial & commercial systems using high current processors
 Telecommunication converters
 DC/DC Power Module
