Product details

Obsolete — sourcing path for sustainment programs

The supply range covers single-cell Li-Ion (3.0V–4.2V), two-cell alkaline (2.4V–3.0V), and regulated 3.3V or 5V rails. This makes the part a fit for handheld and mobile devices where the input voltage drops as the battery discharges.

10 µA quiescent current — standby power budget

At 10 µA supply current, the converter draws negligible current in light-load or shutdown modes. For battery-powered equipment that spends most of its life in standby, this figure directly sets the sleep-mode power budget.

Frequently asked questions

What applications is TPS61121PWRG4 intended for?

The part is listed for Handheld/Mobile Devices — battery-powered portable equipment where wide input range and low quiescent current are critical.
