Hey all,
So I used the TI Webench design tool for the LM25088-1 for an input voltage of 12V to -7V output with 2A current. I created the following schematic:
Here is the board layout:
On power up, the voltage is correct at -7V and works up to loads of -300mA but at any higher load, it immediately current limits (my assumption) and the output goes to -1V. This is a part of a larger power supply test PCB so the voltages and currents can be tested. Did I do something incorrectly? Is the layout an issue in this case?
Let me know and thank you for your time!
Scott
