Meditation, mindfulness
silence and solitude
all mean being quiet in heart
mind and soul
spirit free
eye closed
eye of your soul open
ears alert
do nothing
a comfortable, quiet place, dim light…
Peacefulness
all the feeling of real peace actually come after deep lost or deep struggle, troubles, hardships…It comes from let go, and carry on.
Hope
There is always trust, hope and love.

FP7209XR-G1 SOP-8L(EP) 针对LED驱动程序的非同步PWM启动控制器
一般说明
FP7209是针对LED驱动器的升压拓扑开关调节器。它提供了内置的门驱动销,用于驱动外部N-MOSFET。误差放大器的非反相输入端连接到一个0.25V的参考电压。如UVP、OVP、OCP等,保护系统电路有三个功能。LED电流可以通过一个连接到DIM针脚的外部信号来调整。DIM引脚接受直流电压或PWM信号。PWM信号滤波器组件包含在芯片中。电流模式控制和外部补偿网络使系统易于稳定和灵活。
FP7209可在小足迹SOP-8L(EP)包中使用,以适合为应用领域节省空间的PCB布局。
特征
启动电压:2.8V
宽电源电压工作范围:5V至24V
精密反馈参考电压:0.25V(最大值)
模拟和数字调光控制
关机电流:6μA(最大值)
固定开关频率:150 KHz
输入下电压保护(UVP)
输出过电压保护(OVP)
开关MOSFET过电流保护(OCP)
过温保护(OTP)
包:SOP-8L(EP)
应用
LED模块
显示背光
汽车照明
便携式LED照明

#凝聚v力量##说给刘宇的晚安心语#黄昏时分,小卖部的门灯散着惨淡的光,屋子里灯光沉沉的,屋顶很高,黑影匍匐在各处,我总是恍惚自己走进了妖怪店。
At sunset, the door lamp of the grocery gave off dim light. The heavy light, coupled with high ceilings, projected dark shadows creeping at all corners. This made me feel like wandering into a ghost store.
