Hello, i´m using MP2759GQ to charge a pack consisted of 4S2P. Righ now if i connect the charger to the supply without the battery it´s outputing 16V a normal value for the 4S i selected on the pin. But if i connect the pack the current draw goes up to 2.9A at 24V and just heats up like crazy. i measured the current on the battery and is not going to there, there is only a few miliamps. When the battery is connected the coil also starts making noise, i just can´t find why, there is nothing connected on the power path is just the standalone charger working. Can i get a schematic review and maybe why is not working ?
Here is my schematic.
