Other Parts Discussed in Thread: TPS92641 Hi : 请问下,TPS92641在采用 Shunt FET dimming时,UDIM脚不用再接PWM脚吗?谢谢 TPS92641 UDIM控制输出电压波形延迟较大 Hi, 我们复制了官方的 PMP8016 Demo设计,现在出现一个不是很清楚原因的问题:UDIM 控制输出,发现输出电压波形与UDIM上的波形有延迟。 我们做了...
I have some problems with visible flicker when shunt pwm diming LEDs with a total forward voltage above around 30V (input voltage above around 40V). This seems to originate from the inductor charging while the shunt transistor is conducting (SDIM pin low). Sometimes and seemingly randomly the ...
请问下,TPS92641在16bit PWM 调光下,频率可以去到多少? Johnsin Tao: HiWith this method, only the speed of the parallel Shunt NFET limits the dimming frequency and dimming duty cycle.datasheet没有提到最高调光频率能到多少,但是提到主要受制于 Shunt NFET,可见频率是可以到很高的,具体你希望做到多少...
