Description

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 theoutput voltage. The transitions between modes happen at defined thresholds and avoid unwantedtoggling within the modes to reduce output voltage ripple. The device output voltages areindividually set by a resistive divider within a wide output voltage range.The TPS63805 achieves the lowest solution size with a tiny bill ofmaterials. An 11-µA quiescent current enables the highest efficiency for little to no-loadconditions.

The TPS63806 is optimized for applications where the load-step responseunder a heavy load profile is a concern.

The TPS63805 and TPS63806 come in a1.4 mm x 2.3 mm package.The device works with tiny passive components to keep the overall solution size small.
