Remark

TPS62842DGRR General Description

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 I_Q in 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.

The STOP pin of the device immediately eliminates any switching noise in order to take a noise-free measurement in test and measurement systems.

The TPS62840 provides an output current of up to 750 mA. With an input voltage of 1.8 V to 6.5 V, the device supports multiple power sources such as 2S to 4S Alkaline, 1S to 2S Li-MnO₂, or 1S Li-Ion/Li-SOCl₂.
