数据: LMR14030-Q1 SIMPLE SWITCHER® 40V、3.5A 降压转换器(IQ 为 40µA) 数据表 (Rev. A)
LMR14030-Q1器件是一款集成高侧金属氧化物半导体场效应应晶体管(MOSFET)的40V,3.5A降压稳压器。器件的宽输入电压范围为4V至40V,适用于调节从工业到汽车等各类应用中的非稳压电源。其扩展系列产品能够以引脚到引脚兼容封装提供2 A和5A电流选项,其中包括LMR14020-Q1和LMR14050-Q1。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。并且在断断模式下具有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枯燥工作。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功能:逐周期限流保护,应对耗尽大的热感测和热关断保护以及输出过压保护。
LMR14030-Q1采用带有外露焊盘的8引脚HSOIC或10引脚WSON封装,用于实现低热阻。
