NCP4304A/B 是一款全功能控制器和驱动器,专门为控制开关模式电源中的同步整流电路而设计。由于其多功能性,它可以用于反激、正向和半桥谐振 LLC 等多种拓扑结构中。外部可调最短开关时间的组合有助于抵御 PCB 布局和其他寄生元件产生的振铃。因此,可以保证 SR 系统可靠的无噪声运行。极短关断延迟时间、驱动器的高汲电流能力以及自动封装寄生电感补偿系统可最大程度延长同步整流 MOSFET 导通时间,实现 SMPS 能效的进一步提高。最后,较宽的运行 VCC 范围结合两个版本的驱动器电压箝位,简化了 SR 系统在 24 V 输出应用中的实施。

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.)
