Description

General part information

TPS62840 Series

The TPS62840 is a high-efficiency step-down converter with ultra-low operating quiescent current of typically 60 nA. The device contains special circuitry to achieve just 120 nA IQin 100% mode to further extend battery life near the end of discharge.

The device uses DCS-Control to cleanly power radios and operates with a typical switching frequency of 1.8 MHz. In Power-Save Mode, the device extends the light load efficiency down to a load current range of 1 µA and below.

16 predefined output voltages can be selected by connecting a resistor to pin VSET, making the device flexible for various applications with a minimum amount of external components.
