The Texas Instruments TPS61222DCKT is a DC/DC switching regulator, specifically a boost converter, designed to provide a stable output voltage from a low input source. It supports an input voltage range from 0.7V to 5.5V and delivers a fixed 5V output. This device is characterized by its high efficiency, up to 95% under typical operating conditions, and a very low quiescent current of 5.5µA, making it suitable for battery-powered applications.
The TPS61222DCKT features synchronous rectification for improved efficiency and includes protections such as output overvoltage, overtemperature, and input undervoltage lockout. It has a switch current limit of 0.4A and can operate at switching frequencies up to 2MHz. The device is available in a compact 6-pin SC-70 package, measuring 4.2 mm², suitable for space-constrained designs. Mounting is via surface mount technology.
This boost converter is part of the TPS6122x family, which provides power supply solutions for products powered by single-cell, two-cell, or three-cell batteries, including Li-Ion or Li-polymer types. Its ability to start up into a load at 0.7V input makes it versatile for various power management scenarios.
