TPS63810
Overview
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.
- 1 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 Simplified Schematic
- 47 µH VI 2.2 V to 5.5 V 10 µF LX1 VIN LX2 VOUT EN
