TPS63070RNMR DC-DC Step-Up/Step-Down Buck-Boost Converter IC - 15-VQFN-HR (3x2.5) - Input Voltage 2~16 V - Output Voltage 2.5~9V - 2A Output & Input Current
The TPS63070RNMR is a high efficiency, low quiescent current buck-boost converter suitable for applications where the input voltage can be higher or lower than the output voltage. Output currents can go as high as 2 A in boost mode and in buck mode. The buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters Power Save Mode to maintain high efficiency over a wide load current range. The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the battery.
