Hi Sir,
We met an issue when using TPS92661 , the condition is as below,
The schematic is as below, when using 2 LED as series connection , there is no problem including communication interface(read write data) ,but when LED over 2 LED, the LED is flashing. we don't know why and need your help
The power of LED came from power supply and set 24V 100mA
1). The target is driver 8 LED( PIN LED12(+)-LED4(GND), the other connected to GND as datasheet
2).CLK Freq. = 307kHz for Baud rate = 19200 bps
3).TPS92661 EN set high
4).check PWR bit = 1
5).write PCKDIV = 0x00
6).LEDON(addr 00h-0Eh) =1
7).LEDOFF(addr 20h-2Eh) = 1023
8).ENON(addr B0h-B1h) = FFh
8).ENOFF(addr B2h-B3h) = FFh
9).check Diagnostic reg. OK
10).PWM Freq. = 150Hz(DPWR2[2:0] 0b000,DDEC[1:0] 0b00)
11). Charge Pump Cap :0.1uF
