Tool/software:
Our design condition is Boost output 20V and 40V and Buck maximum LED is turned on only 3 LED (6.5V forward voltage) and maximum 35V on LED with 15 leds.
We want to work Boost at 20V operations.Is it recommended to operate boost at 20V? and with buck led Voltage 6V?
In buck input under volatge maximum UVLO Can be set us 32.1V. So is it not possibe to operate BUCK With 20V boost output?
Below registor was set to 0 or 1.
BCKxUVLO register not allowing us to work the buck at 20V boost output.If i modify the boost volatge to 30V buck coming to normal operating mode.
I am detecting the status below registor as an undervoltage fault during BOOST volatge 20V.
| 0x1E | BCK1STATUS |
| 0x1E | BCK1STATUS |
Do we have any suggestions recommending to operate at Boost at 20V With buck output volatge on LEDS 6V?
