The TPS63810 and TPS63811 are high efficiency, high output current buck-boost converters
fully programmable through I2C. 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.
Two registers, accessible through I2C, set the output voltage,
and a VSEL pin selects which output voltage register is active. Thus the devices can support
dynamic voltage scaling. If the output voltage register is changed during operation or the VSEL pin
is toggled, the device transits in a defined, programmable ramp-rate.
