Hello, I having troubles with LM27761 it's overheating and making a little noise. I use it for a -5V power supply (low current, less than 100mA) and I get -1,8 and the IC is overheating. Vin is 5V and here is the schematic:
Layout:
I measured a few points:
Vout:
Vout aprox -2V instead of -5V
Vin:
That little noise in Vin it's beacause of LM27761 overheating.
Cpout:
C1+ and C1-:
I don't know what's wrong here, my schematic design or my layout desing, I made 4 PCB prototype with this circuit and the same problem it's happening in all of them. Hope I get some help. Thanks.
