  • L6986是一款降压单片开关稳压器,能够提供高达2 A直流电。VREF 电压介于 0.85 V 到 VIN 之间。由于P沟道MOSFET高压侧功率元件,该设备具有100%的占空比操作。宽输入电压范围满足5 V、12 V和24 V电源的规格低功耗模式”(LCM)是专为在空闲模式下处于活动状态的应用而设计的,因此它可以在输出电压纹波受控的轻负载下最大限度地提高效率。低噪声模式”(LNM)使开关频率恒定过载电流范围,满足低噪声应用规范。输出电压监测仪管理任何数字负载(μC,FPGA)的重置相位。RST开路集电极输出还可在开机阶段实现输出电压排序。同步整流,设计用于中重负载下的高效率,开关频率高,使应用规模紧凑。两个功率元件上的脉冲电流感应实现了有效的恒流保护。

    主要特性

    • 2 A DC输出电流
    • 4 V至38 V工作输入电压
    • 低功耗模式或低噪音模式
    • 轻载下30 μA IQ(LCM VOUT = 3.3 V)
    • 8 μA IQ-SHTDWN
    • 可调fSW(250 kHz - 2 MHz)
    • 输出电压从0.85 V到VIN可调
    • 嵌入式输出电压监测仪
    • 同步
    • 软启动时间可调
    • 内部电流限制
    • 过电压保护
    • 输出电压排序
    • 峰值电流模式架构
    • RDSON HS = 180 mΩ, RDSON LS = 150 mΩ
    • 热关机
