Texas Instruments TPS63900 Synchronous Buck-Boost Converter

Texas Instruments TPS63900 High-Efficiency Synchronous Buck-Boost Converter comes with an extremely low quiescent current (75nA typical). The device has 32 user-programmable output voltage settings from 1.8V to 5V. A dynamic voltage-scaling feature lets applications switch between two output voltages during operation, for example, to save power by using a lower system supply voltage during standby operation. With its wide supply voltage range and programmable input current limit (1mA to 100mA and unlimited), the Texas Instruments TPS63900 is ideal for use with a wide range of primary like 3S Alkaline, 1S Li-MnO2 or 1S Li-SOCl2, and secondary battery types. The high-output current capability supports commonly-used RF standards like sub-1-GHz, BLE, LoRa, wM-Bus, and NB-IoT.
