The TPS63805 and TPS63806 are high efficiency, high output current buck-boost converters. Depending on the input voltage, they automatically operate in boost, buck, or in a novel 4-cycle buck-boost mode when the input voltage is approximately equal to the output voltage. The transitions between modes happen at defined thresholds and avoid unwanted toggling within the modes to reduce output voltage ripple. The device output voltages are individually set by a resistive divider within a wide output voltage range. The TPS63805 achieves the lowest solution size with a tiny bill of materials. An 11-μA quiescent current enables the highest efficiency for little to no-load conditions.
