TPS610981DSER in TI TPS6xxxx Bucks & Boosts Family
The TPS61098x family from Texas Instruments consists of ultra-low quiescent current synchronous boost converters with integrated LDOs, specifically designed for single-cell battery applications. These PMICs are engineered to provide a dual power rail solution—an always-on regulated output and a secondary switchable output—while maintaining an exceptionally low IQ of only 300nA. This makes them ideal for extending the battery life of low-power IoT devices and wearables where high efficiency at light loads is mission-critical.
Variants in This Sub-Family
The TPS61098x sub-family variants primarily differ in their factory-preset output voltages for both the boost and LDO rails. While the TPS610981 offers a fixed 3.3V boost and 3.0V LDO, other members like the TPS610982 provide different voltage combinations to suit specific logic levels or sensor requirements. Some variants also offer different power-path configurations to optimize the trade-off between noise isolation and transient response.
