TITPS610981DSER
Overview
The TPS610981DSER is an ultra-low power synchronous boost converter with an integrated LDO, designed for applications powered by single-cell alkaline, NiCd, NiMH, or Li-ion batteries. It features an exceptionally low quiescent current of 300nA in Low Power Mode, allowing it to maintain high efficiency even under light load conditions. The device provides a dual-output solution that combines a regulated boost rail with a secondary LDO or load switch to simplify power sequencing.
Why Choose This Part
This PMIC stands out due to its ultra-low 300nA quiescent current and 88 percent efficiency at 10uA loads. Its 1.5mm x 1.5mm WSON package saves significant board space by integrating both a boost converter and an LDO into a single footprint. The automatic pass-through mode ensures the system remains powered even if the battery voltage exceeds the boost output target.
Applications
Key Specifications
Getting Started
Engineers can evaluate this part using the TPS610981EVM-674 evaluation module to measure efficiency and quiescent current across different load profiles. When designing the PCB, place the input and output capacitors as close as possible to the DSE package pins to minimize parasitic inductance. Use a low-ESR ceramic capacitor for the boost output to ensure stability and low ripple.
