公司介绍
NCP2890 是一款音频功率放大器,适用于手机等便携式通信设备应用。NCP2890 能够通过 5.0 V 电源向 8 Ω 负载提供 1.0 W 的连续平均功率,并通过 2.6 V 电源向 4 Ω 负载提供 320 mW 的连续平均功率。NCP2890 在提供高质量音频的同时,只需要极少的外部组件和最低的功耗。它具有低功耗关断模式,可通过以逻辑低电平驱动关断引脚来实现。NCP2890 包含的电路可防止在开启和关闭转换期间产生杂音。NCP2890 具有最大的灵活性,可提供一个外部控制的增益(带有电阻)以及一个外部控制的开启和关闭时间(带有旁路电容器)。由于其出色的 PSRR,它可以直接连接到电池,节省了 LDO 的使用。该器件采用 9 引脚倒装芯片 CSP 和 Micro8 封装。

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.)
