Texas Instruments TPS63805 High-Efficiency Buck-Boost Converter is a high efficiency, high output current buck-boost converter. The device is employed when the input voltage is higher, equal, or lower than the output voltage. Output currents up to 2A are supported over a wide voltage range.
The device 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. It also automatically changes from the buck to boost operation based on the input voltage. The device remains in a three-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 converter comes in a 1.4mm x 2.3mm package. The device works with tiny passive components to keep the overall solution size small.
