Product description:

TPS61070 Profile
TPS61070 device that uses a single, double or triple-cell alkaline batteries, nickel-cadmium batteries or nickel-hydrogen battery-powered products or single-cell lithium-ion battery or a lithium polymer battery-powered products provide a solution for power. When using When single alkaline battery, TPS61070 variable output current up to 75mA, and discharge the battery down to 0.9V. TPS61070 can also be used to rely on a 3.3V rail or single-cell lithium-ion battery to produce 5V / 200mA output. TPS61070 liter voltage converter with synchronous rectifier based on a fixed frequency, pulse-width modulation (PWM) controllers, designed to achieve maximum efficiency. At low load currents, TPS61070 and TPS61073 enters a power saving mode to a wide range of load currents within maintaining high efficiency is deactivated in TPS61071 and TPS61072, a power-saving mode, thus forcing the converter to operate at a fixed switching frequency. Boost switch maximum peak current is typically limited to 600mA.
TPS61070 output voltage from an external resistor divider. You can disable the converter to minimize battery consumption. During the shutdown, the load is completely disconnected from the battery .TPS61070 6-pin thin SOT23 package (DDC) .
