TPS63070RNMR Description
The TPS63070RNMR is a buck-boost converter with high efficiency and low quiescent current that is appropriate for situations where the input voltage can be greater or lower than the output voltage. In boost and buck modes, output currents can reach up to 2 A. To achieve maximum efficiency, the TPS63070RNMR buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller with synchronous rectification.
