安森美半导体日前推出集成待机和高电压启动功能的组合式PFC/PWM控制器NCP1603。 NCP1603结合一个功率因数校正(PFC)控制器芯片和一个脉冲宽度调制(PWM)控制芯片在一个16引脚SOIC封装中。这一组合既满足功率因数校正和低待机能耗的规范要求,又简化离线、交流一直流电源的设计。该器件的目标应用包括笔记本电脑和LCD适配器以及其他消费类电子产品。 NCP1603在轻载状态下,PWM控制器关闭PFC功能,可节约达
ON Semiconductor has introduced a combination of standby and high-voltage startup PFC / PWM controller NCP1603. The NCP1603 combines a power factor correction (PFC) controller chip and a pulse width modulation (PWM) control chip in a 16-lead SOIC package. This combination meets the regulatory requirements for power factor correction and low standby power while simplifying offline, AC-DC power supply design. Target applications for this device include notebook computers and LCD adapters and other consumer electronics products. NCP1603 PWM controller turns off PFC function at light load, saving up to
