Overview

The TPS62122DRVR is a high-efficiency synchronous step-down converter designed for low-power applications operating from input voltages up to 15V. It provides a regulated output of up to 75mA with an adjustable output voltage range of 1.2V to 5.5V, making it ideal for devices powered by multi-cell batteries or energy harvesting sources.

Why Choose This Part

This regulator features an exceptionally low quiescent current of 11uA and a power-save mode that maintains high efficiency even at light loads. Its wide input voltage range of 2V to 15V and 100 percent duty cycle capability allow for minimal dropout and operation across a broad variety of power sources.

Applications

Energy Harvesting
Efficiently converting erratic power from solar cells or thermal generators into stable rails for low-power sensors.
Battery-Powered IoT Nodes
Extending the life of devices powered by 9V alkaline, Li-MnO2, or Li-SOCI2 batteries.
High-Voltage LDO Replacement
Replacing linear regulators in 12V industrial loops to significantly reduce heat dissipation and power loss.
