    Dear Friend

    I have purchased a eva  board SM3320 BAT-EV Charge controller..We would like to introduce software changes and my implementation requires few ports and addition of I2C devices.I see the following ports of micro chip micro controller 16F722ports are free ,RA0 TO RA7,RB4 ,RB5 and also I2C address dedicated ports.I see RC5 is USED as  address  to communicate with  SM74472 ,where as PC6 and PC7 is not brought..I require all the ports are brought  out for other features implementation.Can get the source file for PCB(GERBER) and the CAD package used.

    Thanks

    Hello,

    I have purchased 5113 driver evaluation boards from TI.

    I had couple of quick questions regarding changing the desired output voltage from 10V to 50V.  Basically, I understand that I will have to change the voltage rating of outputs caps (C13, C14, C1, C12, C10, and C11) from 16V to 100V.  What do I do in the feedback path?  Should I change something in R1/R6/R13?  And secondly, should I do something about Ex Vcc?  Currently, this is being tapped from the 10V output.

    Thanks/Madhav
