sp601 6 e synchronous rectifier driver 201 6 /0 4 / 11 ver 1.0 page 1 description applications the fundamental of sp601 6 e 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, sp601 6 e is designed for resonance. it also maintains the mosfets body diode conduct ion at minimum level. the sp601 6 e is capable to adapt in almost all existing resonance converters with few adjustments considered necessary. ? switching mode power supply (ccm&dcm&qr) ? storage area network power supplies ? telecommunication converters ? embedde d systems ? industrial & commercial systems using high current processors ? power converters to meet lot 6 requirement features pin configuration (so t - 23 - 6l ) ? offers efficiency improvement over schottky diode (depends on drive configuration of the sr). ? 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 3 00 khz. ? synchronize to transformer secondary voltage waveform. ? internal over voltage protection part marking
