Has anyone tangled with the B6284 boost converter IC? It has an enable line that is supposed to shut down the device when connected to ground but I can only get it to drop the output from 12 V to 3 V. Seems bizarre for something as simple as a control pin not to work as advertised. Wondering if I'm missing something?
There's no way for the IC to prevent current from flowing from your supply thru L1 & D1, to the output.
The Enable pin is only intended to switch the Boost converter IC on & off, not act as an output switch.
