Analog Devices DC2966A Demonstration Circuit shows the LTC3376 4-channel configurable buck regulator operating in configuration CFG [3:0] = 0000. This sets the LTC3376 to operate as a quad buck with all four possible outputs, each capable of 3A. By default, outputs 1-4 are set at 5V, 3.3V, 2.5V, and 1.8V, respectively.
