Description

General part information

TPS63900 Series

The TPS63900 device is a high-efficiency synchronous buck-boost converter with an extremely low quiescent current (75 nA typical). The device has 32 user-programmable output voltage settings from 1.8 V to 5 V.

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 (1 mA to 100 mA and unlimited), the device is ideal for use with a wide range of primary like 3S Alkaline, 1S Li-MnO2or 1S Li-SOCl2, and secondary battery types.
