Automatic buck-boost power management chip TPS63070
description
TPS63070 is a high-efficiency buck-boost converter with low quiescent current, suitable for applications where the input voltage may be higher or lower than the output voltage. In boost or buck mode, the output current can be as high as 2A. The buck-boost converter is based on a fixed frequency, pulse width modulation (PWM) controller, which uses synchronous rectification to achieve the highest efficiency. In the case of low load current, the converter enters the power saving mode to maintain high efficiency in a wide range of load current. The converter can be disabled to greatly reduce battery consumption. During shutdown, the load is disconnected from the battery. This device is packaged in a 2.5mm x 3mm QFN package.
