TPS62842DGRR 降压 开关稳压器 的描述：

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

The device uses DCS-Control to cleanly power radios and operates with a typical switchingfrequency of 1.8 MHz. In Power-Save Mode, the device extends the light load efficiency down to aload 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 anoise-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 Vto 6.5 V, the device supports multiple power sources such as 2S to 4S Alkaline, 1S to 2SLi-MnO2, or 1S Li-Ion/Li-SOCl2.
