TMDSSOLARPEXPKIT - my F28035 control card is getting heated

i have recently bought a TMDSSOLARPEXPKIT kit with F28035 control card. i just connected it with pc and 20V power supply, initially i saw LEDs in the control card F28035 glowing then in next few seconds it turned off  then i noticed that IC in control card is getting heated up so i turned off the supply. 

i read the solar explorer hardware guide before giving supply to the kit, i never changed any jumper position.  

can u provide me steps how to start this kit with all jumper and switch position to be set for safe operation? and also can u provide me information on how to connect a  PV to this board (because i never saw any image of this board connected with panel in its guide) i can understand where to connect PV but still i want to make sure, because i dont want to take risk..

regards

    Yogesh,

    I would recommend instead of using the 20V power supply use a current limited power supply at the input and raise the voltage slowly,

    If you see high current (>0.25 Amps) being drawn it means something has gone wrong in the hardware,

    The panel can be connected between BS3 or BS7 and Ground (BS2, BS6) depending on what you need in the final build,

    thanks mr. manish

    1.you want me to use a current limited power supply at the input instead of using 20V dc supply at [M6] JP1. where i'm suppose to give this current limited power supply? do u want me to give it through external power input [M6] TB1?

    2."need one non technical help from you":  i live in south india, i like to know  whether there is a authorized TI centers in south india especially in "chennai" ? if so please provide me their details so that we could take our boards for testing when we're facing hardware problems.
