SP6003A

SP6003A Synchronous Rectifier Driver DESCRIPTION The fundamental of SP6003A 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 SP6003A 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 650 KHz.  Synchronize to transformer secondary voltage PART MARKING waveform. 2020/06/23 Ver.6 Page 1 SP6003A Synchronous Rectifier Driver TYPICAL APPLCATION CIRCUIT PIN DESCRIPTION Pin Symbol Description 1 Timing Discontinuous current filter timing adjustment resistor connection. 2 Pred Capacitor to store previous cycle timing for Catch MOSFET 3 Rapid-Adj Capacitor connection to adju...
