离线 DCM / CCM 反激 PWM 控制器,适用于充电器应用
Obsolete
先进的 PWM 控制器 FAN501A 简化了要求对输出进行 CC 调节的隔离电源设计。输出电流只需利用变压器初级侧的信息即可精确估算,并可通过内部补偿电路进行控制,从而消除了输出电流传感损耗并且无需外部 CC 控制电路。突发模式的运行电流极低 (250 µA),最大限度提高了轻型负载能效,从而符合全球待机模式的能效准则。与在辅助侧使用外部控制电路进行 CC 调节的传统方法相比,FAN501A 可以降低总成本、组件数量、尺寸和重量; 同时提高效率、生产率和系统可靠性。

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.)
