摘要
NCP1200A是新型低功耗离线式电源控制芯片,将时钟发生器、短路保护、前沿消隐等多种功能集成于芯片内部,大大简化了电源设计。介绍并分析了芯片和它的两个重要特性——动态自供电和跳周期模式,并采用该芯片设计了高输入电压微功率反激电源。
NCP1200A,a PWM current-mode controller for off-line supplies featuring low standby power, is introduced. Especially, its two important features—— dynamic self-supply and skipping cycle mode are analyzed in detail and design a flyback supply with good performances using NCP1200A.
