1 Features 3 Description

The TPS6107x devices provide a power supply 1• 90% Efficient Synchronous Boost Converter

solution for products powered by either a one-cell,

– 75-mA Output Current at 3.3 V From 0.9-V two-cell, or three-cell alkaline, NiCd or NiMH, or oneInput

cell Li-ion or Li-polymer battery. Output currents can

– 150-mA Output Current at 3.3 V From 1.8-V go as high as 75 mA while using a single-cell

Input alkaline, and discharge it down to 0.9 V. It can also

be used for generating 5 V at 200 mA from a 3.3-V • Device Quiescent Current: 19 μA (Typ) rail or a Li-ion battery. The boost converter is based

• Input Voltage Range: 0.9 V to 5.5 V on a fixed frequency, pulse-width-modulation (PWM)

• Adjustable Output Voltage Up to 5.5 V controller using a synchronous rectifier to obtain

• Power-Save Mode Version Available for maximum efficiency. At low load currents the

TPS61070 and TPS61073 enter the power-save Improved Efficiency at Low Output Power

mode to maintain a high efficiency over a wide load

• Load Disconnect During Shutdown current range. The power-save mode is disabled in

• Overtemperature Protection the TPS61071 and TPS61072, forcing the converters

• Small 6-Pin Thin SOT23 Package to operate at a fixed switching frequency. The

maximum peak current in the boost switch is typically

limited to a value of 600 mA.
