# TPS62840DLCR (Component)
## Description
Buck Switching Regulator IC Positive Adjustable 1.8V 1 Output 750mA 8-VFDFN
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 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. 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/LiSOCl2
