SP6892
SP6892 is highly integrated flyback multimode QR controller manufactured by SYNC POWER.
DESCRIPTION
SP6892 is a highly integrated flyback multimode QR controller with the SR controller. With the patented technology, SP6892 is placed in the Primary side of the power supply provides fast and better control for the SR MOSFET turning ON and OFF. Through pulse transformer, SP6892 transfers the ON and OFF signal to the secondary side and eliminates the crossing between primary side MOSFET and the secondary side MOSFET. SP6892 is offered in space saving SOP-10 pack design.
APPLICATIONS
- AC/DC switching power adaptor
- Set-top box power supply
- Open-frame switching power supply
- NB Adaptor
- TV/Monitor Standby Power
