Ok so I made a schematic I will provide of this TPS54160. The output voltage is correct at first but when I hook it up to what I want to power it shuts down.
Input is about 48v (coming from PoE+ which is rectified and clean DC)
Output should be 12v (normally is until it is used)
This design was copied from the web bench tool and is meant to power a camera. The camera shouldn't be attempting to draw to much power. Any help or suggestions would be greatly appreciated.
