Hi Tom:
I'm having some issues with my setup. If I remove Q1 then is see a PWM signal where the gate should be. But with Q1 installed the TPS23543 heats up quickly. Any idea where I messed up? Schematic attached. I had to substitute Q1 with ZXMN10B08E6.
Alternatively, Is there a 5V, ~3W reference design that you can recommend?
