Key Features
- Ultra-low 5.5 µA quiescent current enabling efficient boost conversion for energy-harvesting and always-on IoT applications powered by single-cell batteries
- Wide input voltage range of 0.7 V to 5.5 V with 1.2 V nominal operation, supporting boost from depleted alkaline, NiMH, and harvested energy sources
- Hysteretic current-mode control technique providing inherent stability without external compensation and fast transient response across varying load conditions
- Compact 6-pin SOT-23 package with battery charge controller function enabling minimal BOM energy management for wireless sensor nodes
Applications
The V62/12603-01XE is designed for ultra-low-power boost converter applications in wireless sensor nodes, IoT devices, and energy-harvesting systems where the input supply may be a single 1.2 V NiMH cell, a solar cell, or a thermoelectric generator providing as little as 0.7 V. Its 5.5 µA quiescent current allows continuous boost operation without draining small energy storage elements, making it suitable for perpetually powered remote sensors that harvest ambient energy. Battery charge controller designs for single-cell lithium-ion or NiMH packs also leverage its current-mode control and wide input range to manage charging from low-voltage renewable sources.

Frequently Asked Questions
What minimum input voltage does V62/12603-01XE support, and does it work with a single NiMH cell?
The V62/12603-01XE operates from a minimum input voltage of 0.7 V with a nominal input of 1.2 V, making it directly compatible with a single NiMH cell at nominal 1.2 V or even at end-of-discharge around 0.9 V. This allows the boost converter to extract usable energy from nearly depleted NiMH or alkaline cells that would otherwise be discarded.
How does the 5.5 µA quiescent current of V62/12603-01XE extend battery life in energy-harvesting sensor nodes?
At 5.5 µA quiescent current, the V62/12603-01XE draws only 47 mWh per year from a 1.2 V source at idle, compared to 350 mWh for a 40 µA quiescent current converter. For a sensor node that sleeps 99% of the time and draws 1 mA active at 3.3 V output, this 7x improvement in quiescent current extends a 1000 mAh battery life from approximately 2 years to over 10 years in a typical IoT deployment.
What control mode does V62/12603-01XE use, and why is hysteretic current mode beneficial for low-power boost designs?
The V62/12603-01XE uses hysteretic current-mode control, which inherently eliminates the need for an external compensation network that peak-current-mode or voltage-mode converters require. This reduces external component count by 2 to 3 passive components, and the hysteretic topology responds within a single switching cycle to sudden load steps, preventing output voltage droops that would disrupt sensitive microcontroller or RF transceiver circuits during transmission bursts.
For a compact IoT PCB layout, how much board space does V62/12603-01XE's SOT-23 package require?
The 6-pin SOT-23 package of V62/12603-01XE measures approximately 2.9 mm x 1.6 mm, occupying under 5 mm² of PCB area. Combined with a small 4.7 µH inductor and 2 ceramic capacitors typically under 1 mm² each, the complete boost converter circuit fits within a total board area of approximately 15 mm², ideal for miniaturized wearable sensors or coin-cell powered devices where every square millimeter of PCB space is critical.
