TPS61291DRVR in TI TPS6xxxx Bucks & Boosts Family
The TPS61291DRVR is a high-efficiency boost converter from Texas Instruments designed for low-power and portable applications. This sub-family features a unique bypass mode that connects the input directly to the output to minimize battery drain when regulation is not required. It operates with a very low quiescent current of approximately 15nA in bypass mode, making it ideal for systems that spend extended periods in sleep or standby while powered by primary batteries like Li-SOCl2 or Alkaline cells.
Variants in This Sub-Family
Variants within this sub-family primarily differ in their factory-set or pin-selectable output voltage ranges and the current handling capability of the internal MOSFETs. While the TPS61291 focuses on a 700mA switch limit with 15nA bypass, related members in the TPS6xxxx line may offer higher current limits at the cost of higher quiescent current or lack the bypass feature entirely.
