概览

FAN8303 是一个单片、非同步、步降（降压）稳压器，带内部功率 MOSFET。它能在较宽的输入电源范围内实现 2A 的连续输出电流，具有出色的负载和线路调节。电流模式运行提供快速瞬态响应，并简化回路稳定性。故障条件保护包括逐周期电流限制和高温关断。稳压器关断电流不到 40µA。FAN8303 需要极少数量的现成标准外部部件。外部补偿、启用和可编程软启动功能实现了设计优化和灵活性。逐周期电流限制、频率折回和高温关断防止短路输出。

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.)
