Features
• 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
