Texas Instruments TPS6380x High-Efficiency Buck-Boost Converter is a high-efficiency, high-output current buck-boost converter. The device is used when the input voltage is higher, equal or lower than the output voltage. Output currents of up to 2A are supported over a wide voltage range. The TPS6380x limits the peak current at 4.5A in boost mode and 3.5A in buck mode. The device is adjusted to the programmed output voltage. The TPS6380x automatically changes from buck to boost operation based on the input voltage. The device remains in a 3-cycle buck-boost mode when the input voltage is approximately equal to the output voltage. The transitions happen seamlessly and avoid unwanted toggling within the modes. The TPS6380x comes in a 1.4mmx2.3mm package. The device works with tiny passive components to keep the overall solution size small.
