The TPS62125DSGT is a 300mA High Efficiency Synchronous Buck Converter with adjustable enable threshold and hysteresis. This step-down converter is optimized for low and ultralow power applications providing up to 300mA output current. 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 power-down requirements. 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 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 pulse frequency modulation (PFM) mode and transitions seamlessly and automatically in pulse width modulation (PWM) mode at higher load currents.
