    Hi Mano,

    LTC4002 is a switch-mode battery charger. Heating up at no load can mean many things. It would have helped if you started with a working demo board like what we have available and modify parts from there.  PCB layout can be a source of error too. Isolate first the LTC4002 and make it work at different load conditions.
