LP8863-Q1: different current usage between channels

Part Number: LP8863-Q1

Hello Team,

I have 2 Questions below,

1. Customer want to use CH1~3 to 10mA and CH 4~6 to 120mA by using one device. Is it possible? This is for professional monitor, so it should be used analog dimming and setting the PWM dimming threshold to 0%. In my view, there is Resistor for setting current and it has only one resistor so it is hard to use different current by one device. Do you have any idea for using different current by one device?

2.  Is there any other device which can use different current by one device? Input voltage is 20V and Output voltage is 84V, so it requires boost topology.
