This reference design utilizes 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 of between –0.2 V and –0.6 V capable of delivering a maximum of 15 A of current to the load. The output voltage is adjusted by either providing a PWM signal or analog voltage signal to the –Vout Adj connector, referenced to GND. See the Board Schematic for details regarding voltages.
