SP6018E

SP6018E Synchronous Rectifier Driver DESCRIPTION The fundamental of SP6018E 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, SP6018E is designed for Resonance. It also maintains the MOSFET’s body diode conduction at minimum level. The SP6018E is capable to adapt in almost all existing Resonance converters with few adjustments considered necessary. APPLICATIONS  Switching Mode Power Supply (CCM&DCM&QR)  Storage area network power supplies  Telecommunication converters  Embedded systems  Industrial & commercial systems using high current processors  Power converters to meet Lot 6 requirement FEATURES  Offers efficiency improvement over Schottky Diode (depends on drive configuration of the SR). PIN CONFIGURATION (SOP-8)  Low Standby Power to meet DOE Lot 6 requirement.  Drives all logic level Power MOSFET.  Prediction gate timing control.  Minimum MOSFET body diode conduction.  Operating frequency up to 400 KHz. PART MARKING  Synchronize to transformer secondary voltage waveform.  Internal over voltage protection 2020/06/29 Ver 2 Page 1 SP6018E Synchronous Rectifier Driver TYPICAL APPLCATION CIRCUIT PIN DESCRIPTION Pin Symbol 1...
