This is where high-efficiency boost converters, such as the TPS61022RWUR, come into play.
What is a Boost Converter?
A boost converter is a type of DC-DC converter that steps up (or "boosts") the voltage from a lower level to a higher level. This is crucial for applications where the input voltage (such as from a battery or solar panel) is insufficient to meet the voltage requirements of the system. A boost converter operates through an inductor, a switch (typically a transistor ), and a diode, creating an efficient means to step up voltage. The TPS61022RWUR is a particularly notable example of this technology, specifically designed to operate with low-voltage input and deliver high-efficiency performance.

Overcoming Low-Voltage Challenges
In many electronic devices, especially those powered by small batteries, the input voltage is inherently low. For example, a typical coin-cell battery or a low-voltage supercapacitor may output between 0.3V to 1.5V. However, most modern electronics require higher voltages to operate effectively—usually in the range of 3.3V to 5V or more. Without a reliable way to boost the voltage, these low-voltage sources would be insufficient to power the device, leading to reduced performance or complete failure.
This is where the TPS61022RWUR shines. It takes input voltages as low as 0.3V and can provide a stable output voltage, even under varying load conditions. This ensures that devices powered by small, low-voltage sources can operate efficiently without compromising performance.
