I am trying to design my own switching step down power supply using TI parts. The requirements are Input 6V-15V and output 5V fixed, @2A or close.
Now I am aware of the WeBench tool, as a matter of fact I spend hours reading different datasheets and reviewing different designs, but being a beginner and having no experience in building switching power supplies, I could not determine a part number to start with.
What would be a good starting point for me? I will basically construct the circuit on breadboard for now, and measure different things to see if it suits my needs.
Basically I need 5V fixed output, (and would be great if i did not need resistors to determine vout) - around 1.5-3A, and enable pin that is active on high.
I found a LM2596 - which satisfies my basic requirements, with the exception of EN pin being active low. (I need an active HIGH EN pin, because I will use it with hibernate feature of a mcu)
Any help, ideas and pointers in the right direction would be greatly appreciated,
