概览

NCP1599 是一款固定 1 MHz、高输出电流、同步 PWM 转换器，集成了低电阻、高压侧 P 沟道 MOSFET 和低压侧 N 沟道 MOSFET。NCP1599 利用内部补偿的电流模式控制来提供良好的瞬变响应、简化实施和优良的回路稳定性。它可在 3.0 V 至 5.5 V 范围内调节输入电压，输出电压可调节低至 0.8 V，并能够提供高达 3.0 A 的负载电流。NCP1599 包括内部固定开关频率 (FSW) 和内部软启动以限制浪涌电流。其他功能包括逐周期电流限制、短路保护、省电模式和高温关断。

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.)
