SP6019C

SP6019C Synchronous Rectifier Driver DESCRIPTION The fundamental of SP6019C 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. SP6019C is specially suitable for Forward and DC/DC Module. APPLICATIONS  Servers & workstations  Storage area network power supplies  Telecommunication converters  Embedded systems  Industrial & commercial systems using high current processors  DC/DC Power 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.  TDFN3x3 8LC package design PIN CONFIGURATION (TDFN3x3 8LC) PART MARKING 2020/06/29 Ver.3 Page 1 SP6019C Synchronous Rectifier Driver TYPICAL APPLCATION CIRCUIT PIN DESCRIPTION Pin Symbol 1 Timing 2 Pred 3 VR 4 Adj 5 GND 6 MOSG-C 7 Vdd 8 SYNC 9 GND Description Discontinuous current filter timing adjustment resistor connection.
