I used LP8863EVM connect to 6S8P LEDs (LP8860-LEDLOADEVM) ,but LEDs havn't light
I was follow the Quick Start-Up Procedure described in User Guide
• Connect USB cable between EVB and PC
• Connect external power supply to VIN: 12 V (typical), 5-A setting, output not enabled yet.
• Run the LP8863 GUI software and click ”Control” icon on left of GUI, then control window appears as in Figure 9
• Check ”EVM connected” mark on bottom of GUI software
• Press ”IFSEL Pin” button to select I2C interface
• Enable VIN power supply output
• Click ”Enable Pin” button on GUI software: boost converter starts working, and LEDs stay off without PWM input. I find Boost voltage is 42V.
• On PWM input control, check ”Enable” box of PWM input, select frequency and duty from drop-down boxes(50%default), and press ”Update” button,But LED havn't light, LED0-5 Volatge is 23V. Voost voltage is 42V.
So if I miss something?
