Part Number: LP5520 Hi Sir We would like to apply LP5520 to do color sequential lighting for LCOS display. The target maximum driving current would be 25mA for each channel.
The reference circuit as follows.
We have 8pcs red LED string on red channel…
Part Number: LP5520 Hi,
We are currently programming the LP5520, however, we are struggling to reach a maximum current of 60mA per channel and therefore cannot reach a suitable RGB brightness to create bright white light..
In manual mode, the R/G…
Part Number: LP5520 Hi Team,
My customer is studying our LP5520 and there are 4 questions.
1. Could we use same external PWM to control R/G/B output simultaneously? 60mA x 3 = 180mA sink current
2. Could we use all R/G/B output for Read LED only…
Part Number: LP5520 Hi team, I received the following question at my customer:
" We're planning to use the LP5520 on the next iteration of our project, and we're wondering if it is necessary to use the temperature sensor, and how should we implement…
Hi,
The full names of the referenced application notes in the May 2007 datasheet are "Application Note AN1459, LP5520 RGB Backlight Driver Calibration" and "Application Note AN1462, LP5520 RGB Backlight Driver Evaluation Kit"

Part Number: LP5520 Hi,
most of this comes down to the same problem already described in LP5520: LP5520 Calibration :
The datasheet (in its March 2016 revision) lacks a lot of details on how to properly interpret or determine the EEPROM values for…
Part Number: LP5520 Hi all.
Could you answer some questions?
<Question>
①Can I use the separate power supply without using SW / FB pin?
If it is okay to use a separate power supply, can the SW / FB pin be left unconnected?
②I use manual mode…
Part Number: LP5520 Other Parts Discussed in Thread: TLC5973 Hi all Would you mind if we ask LP5520? <Question> Our customer would like to evaluate LP5520, however there is no EVM. Do you have any good idea? As our customer's request, -They would like…
