What are the key features of XPS62841DLCR?
- Ultra-low 60 nA quiescent current in standby enables multi-year battery life in IoT and energy-harvesting applications
- 1.8 V to 6.5 V input range covers single-cell Li-ion, 2-cell alkaline, and supercapacitor power sources with a single converter
- Automatic PWM/PFM switching maintains high efficiency from 1 µA light load to 750 mA full load, eliminating wasted energy during sleep cycles
What is XPS62841DLCR used for?
The XPS62841DLCR is optimized for always-on wireless sensor nodes, Bluetooth Low Energy tags, and IoT edge devices where the 60 nA quiescent current extends CR2032 coin cell life to several years between replacements. Its 1.8 V to 6.5 V input range accommodates both single-cell Li-ion and two-cell alkaline battery chemistries in the same design. The compact SON package and automatic PFM/PWM mode transitions make it a preferred regulator for wearable health monitors and asset tracking devices requiring sustained low-power operation.

Frequently Asked Questions
How low is the XPS62841DLCR quiescent current and how does it extend battery life?
The XPS62841DLCR has a quiescent current of only 60 nA in PFM standby mode, among the lowest available in a 750 mA step-down converter. On a 220 mAh CR2032 coin cell powering a system that draws 10 µA average, the regulator's own quiescent contribution is less than 1% of total current, extending battery life by over 2 years compared to devices with 1 µA IQ.
What output current and input voltage range does XPS62841DLCR support for a multi-chemistry battery charger design?
The XPS62841DLCR delivers up to 750 mA output across a 1.8 V to 6.5 V input range, covering single-cell Li-ion (2.7 V to 4.2 V), two-cell alkaline (1.8 V to 3.2 V), and single-cell LiFePO4 (2.5 V to 3.6 V) battery chemistries. This flexibility reduces SKU count in product families designed to run from different battery types.
For a BLE sensor node that wakes every 10 seconds, which XPS62841DLCR operating mode delivers the best efficiency?
During the inactive periods between BLE advertisements, the XPS62841DLCR automatically enters PFM mode where average supply current drops to the 60 nA quiescent floor. When the BLE radio fires for its 10 ms transmission window drawing up to 15 mA, the converter transitions to PWM mode maintaining output regulation within ±2% at a switching frequency of approximately 4 MHz, providing seamless load-step response.
How does XPS62841DLCR compare to TPS62841 for a new ultra-low-power wearable design?
The XPS62841DLCR is the extended-temperature or enhanced variant of the TPS62841 family, sharing the same SON package footprint and pin assignments for drop-in compatibility. Both deliver 60 nA IQ and 750 mA output current; choosing the XPS variant provides access to Texas Instruments' extended product lifecycle support and may offer improved availability for production builds requiring a 5-year supply window.
