电源输入端 地 功率管驱动电源端 栅极信号输出端 限流端 环路补偿端 功率管漏端 打印信息 SOT23-6L . 2017 SOT-23-6L (TOP VIEW) 标号 43 A M 描述 代表 LN2443 代表晶圆编号 SOT23-6L封装 2 .natlinear. LN2443 应用说明 LN2443 是一款工作于浮地模式的恒压控制器，其应用说明如下： 启动 VIN 上电并通过启动电阻 R1 给 C1 充电，VDD 电压上升。当 VDD 电压上升并超过 UVLO_R 时，芯片通过 GATE 端驱动外置功 率管， VOUT 通过 D2 给 VDD 供电，最终 VOUT=VDD 并达到稳态。 R1 为启动电阻，启动电流 IS=（VIN-VDD.
