Description
The TPS62125 device is a high-efficiency synchronous step-down converter optimized for low and ultralow power applications providing up to 300mA output current. The wide input voltage range of 3 V to 17 V supports 4-cell alkaline and 1- to 4-cell LiIon batteries in series configuration as well as 9-V to 15-V 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 power-down requirements. The enable comparator consumes only 6-µA quiescent current and features an accurate threshold of 1.2 V 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 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. The DCS-Control™ scheme is optimized for low-output ripple voltage in PFM mode in order to reduce output noise to a minimum and features excellent AC load regulation. An open-drain power good output indicates once the output voltage is in regulation.
