The TPS6302x are high efficiency, low quiescent current, non-inverting buck-boost converters suitable for applications that need a regulated output voltage from an input supply that can be higher, lower, or equal to the output voltage. Output currents can go as high as 2 A in boost mode and as high as 4 A in buck mode. The average current in the switches is limited to a typical value of 4 A.
