TPS62840 Overview
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 150 nA IQ 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.
