商品介绍:
High Performance TM PFC+QR Combo Controller


OB6663 is a monolithic IC which integrates a transition mode power factor correction (TM PFC) controller and a Quasi-Resonant (QR) controller. TM PFC provides low system cost solutions with low harmonic distortion and high power factor. QR provides higher efficiency and lower EMI compared to conventional PWM system. The built-in advanced energy saving with high level protections of OB6663 makes it a best candidate for power supplies which need PFC function.


Features:

◆ Integrated transition mode (TM) PFC controller and Quasi-Resonant (QR) PWM controller
◆ Built-in dual output PFC control
◆ Adjustable PFC ON/OFF control
◆ Meet EPS2.0 with less than 300mW standby power consumption
◆ Multi-Mode operation for QR stage
◆ Analog multiplier with built-in THD optimizer for PFC stage
◆ Line feed-forward compensation for PFC stage
◆ Quick startup and enhanced dynamic response for PFC stage
◆ PFC burst mode when light loading and low line input
◆ Minimum QR short circuit power consumption
◆ Audio noise free operation
◆ Available in SOP16 and DIP16 packages,RoHS compliant



Applications:

◆ Notebook Adapter
◆ Open-frame SMPS
◆ White Goods



Typical Application:
