Other Parts Discussed in Thread: BQ4050 Hello Wyatt,
in a battery BMS we had an issue with the charlieplexing, having the 5th LED rotated that was always lit together with the 4th.
We fixed it by setting the 5th LED in the proper way, but now we have…
Part Number: LP8556 Tool/software: Dear team
Lenovo tablet team want to use LP8556 to drive a 6P9S, a LED panel with 6 LED series. 69PS has the following spec, I see with 3V input, 28V output, the required current is 170mA. Is LP8556 able to drive…

The client device uses a single…
Part Number: LP5036 Tool/software: Hi,
Can I connect 3 LEDs in series by LP5036? In case yes, what is the maximum of VLED?
Output pin is current sink, so a dropping resistor in series is not neccessary?
My use case is:
- total 36 RGB, always 3…
Part Number: TPS92692-Q1 Other Parts Discussed in Thread: TPS92692 Tool/software: Hi team,
My customer is using the SEPIC application of TPS92692-Q1. When the input voltage rapidly switches between power-on and power off, the output current fails to…
Part Number: DLP4620SQ1EVM Other Parts Discussed in Thread: LM3409 , LM61480 Tool/software: We're trying to design a new laser driving circuit that doesn't use the LM3409.
The signals that control the time domain from the formatter board to the LED…
Part Number: ISO1228 Tool/software: Hi all,
My customer are testing a prototype using ISO1228. It is used for both Sink and Source. To save space, they do not use LEDs. All LED pins (LED1~8) are NC. They can use them without any problem, but this causes…
