TPS63810
- Input voltage range: 2.2 V to 5.5 V
- Output voltage range: 1.8 V to 5.2 V
- I2C-configurable during operation and shutdown
- VSEL pin to toggle between two output voltage presets
- Output current
- Up to 2.5 A for VI ≥ 2.5 V, VO = 3.3 V
- Up to 2.5 A for VI ≥ 2.8 V, VO = 3.5 V
- High efficiency over entire load range
- Low 13-µA operating quiescent current
- Automatic power save mode and forced PWM mode (I2C-configurable)
- Peak current mode buck-boost architecture
- Defined transitions between buck, buck-boost and boost operation
- Forward and reverse current operation
- Start-up into pre-biased outputs
- Safety and robust operation features
- Integrated soft start
- Overtemperature and overvoltage protection
- True load disconnect during shutdown
- Forward and backward current limit
- Two device options:
- TPS63810: Pre-programmed output voltages (3.3 V, 3.45 V)
- TPS63811: Program output voltages prior to start-up
- Solution size of < 20 mm2 with only four external components
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.
