Part Number: LP8556 Other Parts Discussed in Thread: LP8555 Hi,
We are using the LP8556EVM to drive LED strings on LP8556TM-LEDLOAD board.
Connector J10 is used to connect LED EVB and LP8555 EVB, where there is a 10 ohm resistor between the LED- of each…
Part Number: TPS61177A Other Parts Discussed in Thread: LP8555 , , TCA9543A Hi Folks,
I have an application where I need to control 40 red and 40 blue LEDs. I looked at the LP8555 chip which would allow me to control all 80 LEDs with a single chip but it…
How do you use the lp8555 or lp3943 to produce a linear bar graph? After reviewing these datasheets, these parts do not seem to be comparable except they do something with LEDs. It's like suggesting someone use a high temperature comparitor for increasing…
LP8555 will support 6s11p LED config.
And this device doesn't have EEPROM, but just EPROM and the default value of section 9.2.1.2 is correct.
The max LED current is 50mA, so max boost load current can be 300mA as long as max SW current is not higher…
Hello Ajay,
What are the forward diode voltages of the LED strings for the different colors? What sort of current do you want this to run at?
Looking at the information that you have provided you will most likely need a boosting module if the only rail…

The resolution isn't the problem. I first saw this problem with an input that only…
