Hi,
We have a backlight driver IC requirement for AUO make panel. Below is the panel specification. I have used TPS61196 backlight driver IC. I am giving 200Hz PWM signal and using 6 channels.I have changed the VOVP threshold value by changing the R3 resistor value to 330k. Also changed the R11-100K,R10-68K,R12-400KOHM. But the output is is raising to 100V. Verified VDD is coming 6V. Q1 is not getting switched. Due to this output voltage is coming 24V only. Please let me know what other changes required in values. Also please let me know how to debug the issue and where to probe.
