高性能功率因子校正器(PFC)

 

简介:

OB6561P/OB6563 是高性能的临界模式(Transition Mode)功率因子校正器(PFC)系列。

该系列产品集成了多项昂宝专利技术,对传统的临界模式控制进行了优化设计,使系统易于实现接近于1的功率因子和极低的谐波失真。

 

应用范围:

1、家用电脑电源
2、电视机电源
3、电源适配器
4、照明电源

 

特点:

1、临界导通模式,内置模拟乘法器
2、专利的谐波优化技术实现了极低的谐波失真(<10% @264VAC)
3、系统反馈环路开路保护(Open loop protection)
4、专利技术保证无异音工作
5、电流检测电阻开路保护
6、间歇工作模式实现轻载高效率
7、可外接信号进行使能控制
8、三重过压保护
9、电流检测回路内置双重噪声抑制功能,无需外加RC低通滤波器
10、逐周期峰值电流限制
11、更低的动态OVP检测电流(OB6563),与PWM结合使用时在150W系统中实现超低(<0.4W)的待机功耗
12、目前提供DIP8、SOP8两种封装形式,符合RoHS标准

High Performance PFC Controller


OB6561P/OB6563
is a high performance transition mode(TM) Power Factor Correction(PFC) control IC. Designed with On-Bright patented proprietary technology, OB6561P/OB6563 optimizes tradition transition mode control easily achieving system power factor to close to 1 with very low THD. OB6561P/OB6563 is full compliant with both IEC61000-3-2 and JEIDA- MITI requirements on THD control.


Features:

◆ Transition mode operation with built-in analog multiplier

◆ System open loop protection
◆ Proprietary audio noise elimination
◆ Dynamic and static output over voltage protection(OVP)
◆ Cycle-by-Cycle current limiting
◆ Burst mode control for improved efficiency at light load
◆ External ENA/disable control
◆ Under voltage lockout with hysteresis (UVLO)
◆ Built in current sense filter, no external RC filter is needed
◆ Green mode operation (OB6563)
◆ Available in DIP8 and SOP8 packages,RoHS compliant



Applications:

◆ LCD TV POWER Supply
◆ Adapter
◆ PC Power
◆ Lighting Power
