I the datasheet, the only typical value is defined for ICTL.
what is the maximum ICTL?
I need to choose opamp which can sink ICTL current from LTM8042.
There are few micro modules in the website that you can check. You may start with LTM8042 to drive 8 LEDs. You can use four of these. Thanks!
Please check these: the analog dimming is not as fine though.
