NCP5030 是一款固定频率 PWM 降压-升压转换器,适用于驱动大功率白色 LED 等恒定电流应用。降压-升压在 H 桥拓扑结构中实施,具有自适应结构,以三种模式之一运行:升压、降压-升压或降压,具体取决于输入和输出电压条件。此器件适用于在便携式应用中实现高能效,能够为手电筒/探照灯应用以高达 900 mA 的直流电路驱动大功率 LED。为了保护该器件,结合了按周期电流限制和高温关断电路,以及输出过电压保护。700 kHz 开关频率允许使用低值 4.7 µH 和陶瓷电容器。

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.)
