2.2 Low Iq

For some applications using batteries for input, to achieve longer battery life, they often require a very low quiescent current (Iq) and high efficiency at both full and light loads. Because most of the device lifetime is spent in low-power states, quiescent currents, subsystem shutdown currents, and high efficiency are very important, as these standby currents can have significant impacts on overall battery life.

TPS62xxx series converters are mainly low Iq devices with less than 30 uA quiescent current and high light-load efficiency. They are mostly using DCS-control™ mode.
