What are the key features of TSP63900?
- Ultra-low 200 nA quiescent current for longest possible battery life in IoT devices
- Wide 1.8 V to 5.5 V input voltage range covers single-cell Li-ion through multi-cell alkaline
- 400 mA output current capability supports wireless SoCs and sensor modules
- Buck-boost topology maintains regulated output whether input is above or below output voltage
- Small no-lead package enabling compact PCB designs for wearable and portable electronics
What is TSP63900 used for?
The TSP63900 is designed for ultra-low power IoT devices, wearable health monitors, and wireless sensor nodes where extending battery runtime is the primary design goal. Its 200 nA quiescent current makes it ideal for applications spending most of their time in deep sleep at 1.8 V to 5.5 V input. The buck-boost topology allows the device to power Bluetooth Low Energy modules, GNSS receivers, and NFC front ends from single-cell batteries throughout their entire discharge cycle.

Frequently Asked Questions
How low is the quiescent current of TSP63900 and how does it extend battery life in sleep-heavy IoT applications?
The TSP63900 achieves only 200 nA quiescent current, enabling IoT devices that spend 99% of their time in sleep mode to operate for years on a single coin cell, far outperforming conventional converters with 10 µA to 100 µA quiescent current in the same 400 mA output scenario.
For a single-cell lithium-ion battery design, how does TSP63900's buck-boost topology maintain regulation throughout the battery discharge curve?
The TSP63900 buck-boost topology regulates output from 1.8 V to 5.5 V input, allowing a single Li-ion cell discharging from 4.2 V to 2.5 V to continuously power a 3.3 V system at up to 400 mA without output dropout that would occur with a simple LDO regulator.
What output current does TSP63900 provide and which wireless modules can it directly power?
The TSP63900 delivers up to 400 mA continuous output current, sufficient to directly power Bluetooth Low Energy SoCs, LoRa modules during 100 mA to 300 mA transmit bursts, and NFC controllers operating at 1.8 V to 5.5 V input without additional power stage components.
How does TSP63900's quiescent current of 200 nA compare to TPS63031 for choosing between them in a wearable design?
The TSP63900 achieves 200 nA quiescent current versus approximately 50 µA for the TPS63031, making the TSP63900 250 times more efficient during sleep mode, which is the deciding factor for wearable designs requiring 400 mA burst current but predominantly operating in low-duty-cycle sleep states.
