Hi,
I am trying to make a synchronous buck converter with 5V/6A output, and I'm trying to reach high efficiency with minimum cost. So I want to use a buck converter IC with an half-bridge MOSFET driver and 2 MOSFETs.
The MOSFET driver I plan to use is TPS28225. I am in search of a buck converter controller IC. I found LM3475 is cheap and its control method looks interesting. But this is designed to drive a P-Channel MOSFET, so I'm not sure if it will work with my MOSFET driver.
Also LM3475 and TPS28225's supply voltage ranges isn't enough for my project, which is going to be supplied with a 4S Li-ion battery(up to 16.8V). Can I use a 5V LDO to supply LM3475 and TPS28225 but switch higher voltages with MOSFETs?
Thanks in advance...
