Part Number: TLC5955 Other Parts Discussed in Thread: LP5891 , TLC6983 , TLC6984 , TLC5946 , LP5890 Hello,
Simple question heres. 1. Because GSCLK requires a constant 33MHz signal. Can I just supply a 33MHz oscillator as the input here? 2. If a short…

Hi there,
I have 24 different LEDs (5 red, 5 blue, 5 green, 4 white, 5 orange) that need between 8-20mA, depending on the LED colour. I would like to use the 24 channel, 30mA…
Hi, Betty,
1. Please be noted system level ESD is not the same as our chip ESD. Customer can use resistors on the output.
2. The SPI signal just turn on/off the channels and when the channel is ON, the current is constant and set by Riref.

Hi, Takahiro-san,
It's possible to achieve independent dimming of each channel.
You're correct and it's controlled by seting ON/OFF time. For example, turning ON for 100 us and OFF for 900 us achieves 10% duty cycle.
We also have PWM type LED driver…
Hi, Takahiro-san,
I've answered your question in your formmer post:

For this original post, if you are looking for an I2C interface LED driver, TLC59116 has 16 channels and can support Vled up to 20V.
If SPI interface…
Other Parts Discussed in Thread: TLC5951 , TLC5947 , TLC5946 I have been evaluating the TLC5946 and TLC5947 and have successfully driven an rgb led with both. I am now considering the TLC5951 as it appears to be cheaper and offers more functionality,…
Hello Rick,
The IC is intended for applications which show static pictures for a longer period of time. So whenever the picture is changing, BLANK can be set high to turn the outputs off and reset the GS counter and during BLANK=high, XLAT can be used…
Other Parts Discussed in Thread: TLC5946 Hello,
I wish to drive between 5-7 RGB LEDs in a portable application (5 - 7 x RGB LEDs = 15 - 21 channels). Only one will be active at a time - perhaps 10-12mA while active (sometimes the single LED will be…
