Other Parts Discussed in Thread: TPS92691
hi E2e,
The schematic is as follow. We use TPS92691QPWPQ1 to drive 8 LEDs. Rated current 1A, maximum current 1.5A. The main problem is that when the LED lights up, there will be buzz on the PCB board (near the chip), please help to analyze the reasons. Thank you.
BRs,
Yuan
