描述

The TPS63810 and TPS63811 are high efficiency, high output current buck-boost convertersfully programmable through I2C. Depending on the input voltage, theyautomatically operate in boost, buck or in a novel 4-cycle buck-boost mode when the input voltageis approximately equal to the output voltage.

The transitions between modes happen at defined thresholds and avoid unwanted togglingwithin the modes to reduce output voltage ripple.

Two registers, accessible through I2C, set the output voltage,and a VSEL pin selects which output voltage register is active. Thus the devices can supportdynamic voltage scaling. If the output voltage register is changed during operation or the VSEL pinis toggled, the device transits in a defined, programmable ramp-rate.
