TPS62125DSGT General Description

The TPS62125DSGT is a versatile synchronous step-down converter designed for low and ultralow power applications, offering a maximum output current of 300 mA. Its input voltage range of 3 V to 17 V makes it suitable for a variety of battery configurations, including 4-cell alkaline and 1- to 4-cell Li-Ion batteries in series, as well as 9-V to 15-V powered devices. One of its standout features is the precise low-power enable comparator, which can function as a supply voltage supervisor to manage power-up and power-down sequences effectively. This comparator consumes minimal quiescent current (6 µA) and boasts an accurate threshold of 1.2 V, along with adjustable hysteresis
