This reference design uses a synchronous-buck regulator with internal top and bottom FETs which is configured as a synchronous-inverting buck-boost converter to provide an adjustable output between -0.2 V and -0.6 V capable of delivering a maximum 15 A of current to the load. The output voltage is adjusted by either an external-PWM signal or analog-voltage signal.
