By Technology
与具有固定开关频率的传统硬开关转换器相比,准谐振转换器 (QRC) 通常具有更低的 EMI 和更高的功率转换效率。FSQ 系列是一款集成的脉宽调制 (PWM) 控制器和 SenseFET,专用于准谐振运行和交替谷开关 (AVS)。该 PWM 控制器包括集成的固定频率振荡器、欠压锁定 (UVLO)、前缘间隔 (LEB)、优化的门极驱动器、内部软启动、用于回路补偿的温度补偿精确电流源,以及自我保护电路。与分立 MOSFET 和 PWM 控制器方案相比,FSQ 系列可以降低总成本、部件数量、尺寸和重量;同时提高了能效、生产力和系统可靠性。此器件为准谐振开关反激转换器的成本高效设计提供了基本平台。

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.)
