LNK306GN产品简介中文资料功能描述  

LNK306GN用来替代输出电流小于360mA的所有线性及电容降压式非隔离电源。其系统成本与所替代的电源相等，但性能更好、效率更高。LinkSwitch-TN在一片IC上面集成了一个700V的功率MOSFET、振荡器、简单的开/关控制电路、高压开关电流源、频率调制、逐周期的电流限制及过温保护电路。器件在启动及工作期间的功率消耗直接由漏极引脚的电压来提供，因此在BUCK及反激式转换器中可节省偏置供电的相关电路。在LNK304-306器件中完全集成的自动重启动电路在短路、开环的故障情况下，安全地限制了输出功率，减少了元器件的数目，降低了在系统级用于负载保护电路的成本。如有必要，IC的自供电操作允许使用没有安规要求的光耦器作为电平转换，以改善输入电压调整率及负载调整率。LNK306GN产品特色功能描述LNK306GN说明：成本最低，元件数目最少的降压转换器解决方案严格的容差和微小的温度漂移特性系统级的过载过热保护、输出短路以及开环故障保护支持降压、降压-升压和反激式拓扑优良的线电压调整率和负载调整率（采用典型配置）高带宽提供快速的无过冲启动电流限流操作方式抑制了线电压纹波通用输入电压范围（85至265 VAC）内置式电流限制和迟滞热关断保护比无源解决方案更高效具有比馈电容解决方案更高的功率因数电源可以实现100%的SMD设计LNK306GN devices integrate a 700 V power MOSFET, oscillator, simple On/Off control scheme, a high voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry in buck or  fl yback converters. The fully integrated auto-restart circuit in the LNK304-306 safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost. A local supply provided by the IC allows use of a non-safety graded optocoupler acting as a level shifter to further enhance line and load regulation performance in buck and buck-boost converters, if required.LNK306GN is specifi  cally designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy effi ciency.有关LNK306GN代理、LNK306GN中文资料、LNK306GN应用电路、LNK306GN引脚功能、LNK306GN原理图、LNK306GN型号封装、LNK306GN PDF、LNK306GN价格、LNK306GN厂家图片、LNK306GN现货供应信息，欢迎来电咨询!
