TPS62742DSST Information

Smart Sensor Solutions
Texas Instruments, a leading IC manufacturer of Point of Load converters, and Würth Elektronik, a leading manufacturer of miniature high performance inductors, are together providing highly efficient low power DC/DC converter solutions. Today's smart and intelligent solutions need to be created with the maximum possible power savings. Whether the energy source is energy harvesting, battery-/capacitor-powered, or from power grid, power conversion must become as efficient as possible to conserve available energy within the circuit.Learn More
TPS62740/TPS62742 360nA IQ Step-Down Converter
Texas Instruments TPS62740/TPS62742 360nA IQ Step-Down Converter is industry's first step down converter featuring typical 360nA quiescent current and operating with a tiny 2.2µH inductor and 10µF output capacitor. This new DCS-Control™ based device extends the light load efficiency range below 10µA load currents. The device operates from rechargeable Li-Ion batteries, Li-primary battery chemistries such as Li-SOCl2, Li-MnO2 and two or three cell alkaline batteries. The input voltage range up to 5.5V allows also operation from a USB port and thin-film solar modules. The output voltage is user selectable by four VSEL pins within a range from 1.8V to 3.3V in 100mV steps. TPS62740/TPS62742 features low output ripple voltage and low noise with a small output capacitor. Once the battery voltage comes close to the output voltage (close to 100% duty cycle) the device enters no ripple 100% mode operation to prevent an increase of output ripple voltage. The device then stops switching and the output is connected to the input voltage. The integrated slew rate controlled load switch provides typ. 0.6Ω on-resistance and can distribute the selected output voltage to a temporarily used sub-system.
