The TPS62125 is a high efficiency synchronous step
down converter optimized for low and ultra low power
applications providing up to 300mA output current.
The wide input voltage range of 3V to 17V supports
four cell alkaline and 1 to 4 cell Li-Ion batteries in
series configuration as well as 9V to 15V powered
applications. The device includes a precise low power
enable comparator which can be used as an input
supply voltage supervisor (SVS) to address system
specific power up and down requirements. The
enable comparator consumes only 6μA quiescent
current and features an accurate threshold of 1.2V
typical as well as an adjustable hysteresis. With this
feature, the converter can generate a power supply
rail by extracting energy from a storage capacitor fed
from high impedance sources such as solar panels or
current loops. With its DCS - Control TM scheme the
converter provides power save mode operation to
maintain highest efficiency over the entire load
current range. At light loads the converter operates in
PFM mode (pulse frequency modulation) and
transitions seamlessly and automatically in PWM
(pulse width modulation) mode at higher load
currents. The DCS - Control TM scheme is optimized
