Maxim Integrated MAX17223ENT+ NanoPower Boost Converter

The MAX17223ENT+ is a high-efficiency, compact, synchronous boost converter designed by Maxim Integrated to meet the demands of space-constrained, battery-powered applications. This powerful component is well-suited for devices that require a small, efficient, and reliable power source to extend battery life while maintaining a stable output voltage.

One of the standout features of the MAX17223ENT+ is its NanoPower technology, which ensures ultra-low quiescent current. This characteristic is particularly beneficial for portable devices, as it minimizes the power drain when the device is in standby mode, thereby significantly extending the battery life. With a quiescent current of just 300nA, the MAX17223ENT+ is an excellent choice for energy-sensitive applications such as wearables, wireless sensors, and medical devices.

The MAX17223ENT+ operates over a wide input voltage range from 0.4V to 5.5V, making it versatile enough to be powered by various battery chemistries, including alkaline, NiMH, and lithium cells. This flexibility allows designers to use the converter in multiple product designs without the need to reconfigure the power supply architecture.

With its integrated synchronous rectifier, the MAX17223ENT+ achieves high efficiency across a broad range of load conditions. This efficiency is crucial for maximizing battery life and reducing heat generation in small, enclosed spaces. The boost converter can deliver up to 225mA of output current at 3.3V in a 1.8V input scenario, which is sufficient for a wide range of low-power applications.

The device comes in a tiny, 6-pin thin SOT23 package, ensuring a minimal footprint on the PCB. This small size is essential for modern electronic devices where space is at a premium. Additionally, the MAX17223ENT+ features a True Shutdown™ mode that disconnects the output from the input with no forward or reverse current, providing additional protection for sensitive downstream components.

Overall, the Maxim Integrated MAX17223ENT+ is a robust, efficient, and versatile power solution that is ideal for designers looking to enhance the performance and battery life of their compact, portable devices.
