Key Features
- Ultra-low 75 nA quiescent current extending battery life in energy-harvesting and always-on IoT sensor nodes
- Wide 1.8 V to 5.5 V input range covering single-cell Li-ion throughout its full discharge curve with 1 A output capability
- Tiny 12-ball WCSP package minimizing PCB footprint for ultra-compact wearable and coin-cell-powered device designs
Applications
The TPS63901YCJR is optimized for coin-cell, single-cell lithium-ion, and energy-harvesting powered IoT devices where the 75 nA quiescent current preserves charge during long sleep intervals. It serves wireless sensor nodes, smart tags, and wearable health monitors that demand continuous, regulated output from a supply that spans 1.8 V to 5.5 V. The WCSP package enables sub-millimeter-thin PCB designs in hearing aids, medical patches, and asset tracking badges.

Frequently Asked Questions
How does the 75 nA quiescent current of TPS63901YCJR compare to typical buck-boost converters for battery life?
At 75 nA IQ, the TPS63901YCJR draws roughly 10 to 100 times less standby current than conventional buck-boost regulators, which often exceed 5 µA to 50 µA in light-load mode. In a coin-cell application drawing an average of 1 µA system current, the converter's self-consumption contributes less than 8 % of the total budget, dramatically extending operational life beyond 1 year on a single CR2032 cell.
Which input voltage range does TPS63901YCJR support, and how does that map to common battery chemistries?
The TPS63901YCJR accepts inputs from 1.8 V to 5.5 V, which covers a single-cell lithium-ion battery across its full discharge range of approximately 3.0 V to 4.2 V, as well as alkaline cells down to 1.8 V and small supercapacitor stacks up to 5.5 V. This broad 3.7 V input span eliminates the need for chemistry-specific converter selection in multi-product platforms.
For a compact wearable PCB, how does the WCSP package of TPS63901YCJR reduce board space compared to a standard SOT package?
The 12-ball WCSP package of TPS63901YCJR measures approximately 1.6 mm × 1.6 mm with a 0.5 mm pitch, occupying less than 2.6 mm² of board area. A comparable SOT-23-5 or SOT-23-6 package typically requires 8 mm² to 12 mm² including recommended land patterns, meaning the WCSP cuts footprint by up to 75 %, which is critical for sub-10 mm² power-rail budgets in hearing aids and medical patches.
