Paralleling LM2576
Is this a good circuit to build, how can I suggest MOSFET power dissipation? Is this a good MOSFET choice? How can I minimize switching loss?

Paralleling LM2576
Quote:Why not feed the motor directly from the 53V and PWM it so it effectively sees 12V? Sounds like a good paln,how do I limit the current to 8Amps, how do I calculate PWM value...

Paralleling LM2576
So what is the proper way of paralleling them? can I put a series diode and series 0.1 ohm resistor in their output and set their voltages 12.7 volt, so when one regulator has a...

Variable array size
Each alarm uses about 32 bytes of ram and I have used ATXMEGA128A1,

Variable array size
Dear Guys Thanks for all your feedback's,the maximum number of alarms is 20 and if the user select the inputs to do something else the number of alarms would be less, Maybe I...

Variable array size
Ok would you tell me a simple example? for example rewrite the above code that I have shown to you?

Variable array size
I have not used malloc() and linked list before,and I have no idea about using them? I think in this way I have to change alot in my code!!! Do we have any easier way?

Variable array size
I have designed a system, and have defined several things based on the number_of_alarms (for loops, arrays ,structs ,etc...),and in my system currently the number_of_alarms is...
