New step-down converter features 360nA quiescent current

This post sponsored by Texas Instruments.

The TPS62740 is the industry’s first step-down converter featuring typ. 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. TPS62740 supports output currents up to 300mA. It 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 features low output ripple voltage and low noise with a small output capacitor. Once the battery voltage comes close to the output voltage, the device enters no-ripple 100% mode operation to prevent an increase of output ripple voltage. It 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.
