The TPS62742DSST is a Step-down Converter features 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 current. It supports output current up to 400mA. 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 1.8 to 3.3V in 100mV steps. It 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 vol
