LYTSwitch-0产品系列专门为低成本LED灯泡和T8灯管应用而设计。LYTSwitch-0器件在一个单片IC上集成了一个700 V功率MOSFET、振荡器、开/关控制方案、EMI降低和多种控制功能(包括逐周期检测的电流限流及热关断电路)。
LYTSwitch-0产品系列可以为成本竞争非常激烈的LED照明应用提供低元件数的非隔离开关式拓扑结构。
66 kHz的工作频率加上频率抖动功能,可大幅降低EMI滤波器的成本。
启动及工作时的功率直接来自于漏极引脚的电压,无需使用偏置电源及相关电路。
采用LYTSwitch-0系列器件的设计可轻松满足欧洲和北美对消费类照明应用规定的PFC标准。
具有严格输入电压调整率和负载调整率的精确恒流控制,在宽温度范围内表现稳定,使LYTSwitch-0非常适合LED照明应用。
用于短路、开路和开环故障的集成式自动重启动以及迟滞过热保护功能(135°C) ,可以在不增加额外成本的情况下提供全面的保护。
LYTSwitch-0产品系列同时支持降压式、降压-升压式非隔离反激式以及升压式拓扑结构。700 V开关功率MOSFET支持85 VAC至308 VAC的���入电压范围。
提供针对直插式和表面贴装的封装选项,可满足不同的制造要求。
