I have a question about TPS54060A.
Please tell us the efficiency at inverting circuit.
Vin=12V
Vout=-5V
Iout=1A
Best regards,

Takahiro-san,
TPS54060A is a 0.5A device. You will need a higher-current device to get 1A out.
The slva317b app note shows TPS54060A with VIN=24V, VOUT=-12V. The efficiency is 90% at 350mA.
