数据： LMR14020 SIMPLE SWITCHER® 40V 2A、2.2MHz 降压转换器，具有 40μA IQ 数据表 (Rev. A)
LMR14020器件是一款具有集成型高侧MOSFET的40V，2A降压稳压器。该器件具有4V至40V的宽输入电压范围，适用于从工业到汽车各类应用中非稳压电源的电源调节。该稳压器在休眠模式下的静态电流为40μA，非常适合电池供电类系统。并且在关断模式下具有1μA的超低电流，可进一步延长电池使用寿命。该稳压器的可调开关频率范围较宽，这使得效率或外部元件尺寸能够得到优化。内部环路补偿意味着用户不用承担设计环路补偿组件的脱水工作。并且还能够以最大限度减少器件的外部元件数。精密使能输入简化了稳压器控制和系统电源排序。此外，该器件还内置多种保护特性：逐周期电流限制保护，应对功耗过大的热感测和热关断保护，以及输出过压保护。
