TPS61221DCKT in TI TPS6xxxx Bucks & Boosts Family
The TPS6122x family by Texas Instruments consists of high-efficiency synchronous step-up converters designed for battery-powered systems. Operating from an input voltage as low as 0.7V, these boost regulators provide a reliable 3.3V or 5V fixed output (or adjustable versions) while maintaining an ultra-low quiescent current of only 5.5 microamps. This family is specifically engineered to maximize battery life in single-cell alkaline, NiCd, or NiMH applications where space and power efficiency are critical constraints.
Variants in This Sub-Family
Variants within the TPS6122x sub-family are distinguished primarily by their output voltage configurations. The TPS61221 provides a fixed 3.3V output, while the TPS61222 offers a fixed 5.0V output, and the TPS61220 serves as an adjustable version where the output can be set between 1.8V and 5.5V via an external resistor divider. All variants share the same SC-70 package footprint and input voltage range, allowing for easy design migration.
