Are there any reference layouts for the LM3478 or is layout advice available anywhere? I've built a 10V 5A design using all the parts produced in Webench, and I get 10V out until I load it, then the output falls away at relatively low currents. I'm assuming that this is due to noise on the sense input, since the gate pulses have a very short duration and don't appear to get any longer when I increase the load.
Hey Phil,
I will send you one of our demo board layout. The source file will be in Altium. Can you work with it or would you like to have the gerber files?
Also can you please share your Webench design with us so we can review your design to see why it's not regulating at load.
Here is my email address: Howard.chen@ti.com
