FAN7340 是一款单通道升压控制器,集成了 N 沟道功率 MOSFET,可实现 PWM 调光,采用安森美半导体的专属平面双扩散 MOS (DMOS) 工艺。该集成电路作为恒定电流电源运行,用于驱动高电流 LED。它使用电流模式控制和可编程斜率补偿来防止亚谐波振荡。该集成电路提供开路 LED 保护、过电压保护和直连短路保护,可实现系统高可靠性。如果发生异常 LED 串情况,该集成电路则生成带延迟的故障信号。PWM 调光和模拟调光功能可独立实施。内部软启动可防止涌入电流在启动时流入输出电容器。

Re-calculate Data
Data is based on the following assumptions.
Note: The temperature and confidence level may be adjusted to your requirements.
Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
