公司介绍
高度集成的 FAN4800AS/CS/01S/02S 部件特别适用于包含升压 PFC 和 PWM 的电源。它们需要极少的外部组件即可实现多种保护/补偿。它们采用 16 引脚 DIP 和 SOP 封装。PWM 可在电流模式或电压模式下使用。在电压模式下,来自 PFC 输出总线的前馈可以降低辅助输出波纹。与以前的产品 ML4800 和 FAN4800 相比,FAN4800AS/CS/01S/02S 的运行电流更低,可以节省外部器件的功耗。FAN4800AS/CS/01S/02S 具有准确的 49.9% 最大 PWM 占比,使得保持运行时间更长。ML4800 和 FAN4800 中没有该系列提供的欠电压保护和 PFC 软启动功能。 要评估 FAN4800AS / CS / 01S / 02S 是否适合替换现有的 FAN4800 和 ML4800 板,必须在微调程序前完成五个任务:1. 将 RAC 电阻从旧值更改为更高值的电阻:介于 6MΩ 和 8MΩ 之间。 2. 将 RT/CT 引脚从现有值更改为 RT=6.8 kΩ 和 CT=1000 pF,以便 fPFC=64 kHz 和 fPWM=64 kHz。 3. VRMS 引脚在 VIN=85 VAC 时必须为 1.224 V 才能在 85 VAC 到 270 VAC 的线路输入中应用通用输入。 4 在满负载下,平均 VVEA 必须为 ~4.5V,VVEA 的波纹必须小于 400 mV。 5. 对于软启动引脚,软启动电流已降至 FAN4800 电容器的一半。 从 FAN4800A/C/01/02 到 FAN4800AS/CS/01S/02S 有两个区别:1. 欠压保护的反跳时间延长到一秒。2. PWM 门极箝位电压提高至 19V。
