The TPS61222DCKR is a highly efficient, synchronous boost converter from Texas Instruments. It is designed to provide a regulated output voltage from a single cell alkaline, NiMH, or NiCd battery, or from a 2-cell battery pack, with an input voltage range of 0.35V to 5.5V. With an integrated, low RDS(ON) power MOSFETs, this boost converter achieves high efficiency over a wide range of load currents. The TPS61222DCKR is capable of delivering a maximum output current of 1.2A when working with a 5V input voltage. It also offers excellent load and line regulation, allowing for stable output voltage performance. One of the key features of the TPS61222DCKR is its ability to automatically transition into and out of a power-save mode, depending on the load. This helps to conserve battery power and extend the battery life. Additionally, the TPS61222DCKR incorporates a variety of protection features such as over-temperature, over-current, and under-voltage lockout. This boost converter is offered in a small, space-saving package, making it ideal for portable and battery-powered applications. Whether you need to power sensors, microcontrollers, or other low-power devices, the TPS61222DCKR is an efficient and reliable solution.
