概览

NCP1034是一款高电压PWM控制器，适用于高性能同步降压DC-DC应用。NCP1034驱动一对可编程开关频率高达500kHz的外部N-MOSFET，因此可以灵活调节IC运行，满足系统级要求。外部同步功能简化了系统级滤波器设计。输出电压可通过内部1.25V基准电压精确调节，适用于低电压应用。提供了欠压锁定和hiccup电流限制等功能，可在发生故障时提供必要的系统级安全保护。

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.)
