Maxim Integrated's MAX828EUK-T: High-Efficiency Charge-Pump Voltage Inverter

The MAX828EUK-T is a compact, high-efficiency charge-pump voltage inverter designed by Maxim Integrated. This versatile component is engineered to provide a reliable and stable negative voltage supply for various applications. Its primary function is to invert a positive voltage to a corresponding negative voltage, making it an ideal solution for systems that require a dual supply from a single positive input.

Constructed with a minimalistic design in mind, the MAX828EUK-T comes in a tiny 5-pin SOT-23 package, which is highly beneficial for space-constrained applications. Despite its small size, this charge-pump voltage inverter is capable of delivering up to 25mA of output current, catering to a broad range of low-power devices.

The device operates over a wide input voltage range of +2.5V to +5.5V, ensuring compatibility with most standard logic levels and battery-operated circuits. It boasts a high conversion efficiency, which is achieved through an internal 35kHz (typical) oscillator that reduces the size of the external capacitors required, thus saving board space and component costs.

One of the key features of the MAX828EUK-T is its low quiescent current, which makes it an excellent choice for battery-powered devices where power conservation is crucial. Additionally, the device includes an onboard oscillator, eliminating the need for external frequency-setting components and further simplifying the design.

The MAX828EUK-T is also equipped with thermal-shutdown protection, safeguarding the device from potential damage caused by excessive temperatures. This feature enhances the overall reliability and longevity of the product when deployed in challenging environmental conditions.

In summary, the MAX828EUK-T from Maxim Integrated is a highly efficient, space-saving charge-pump voltage inverter that is perfect for portable electronics, battery management systems, and other applications requiring a compact negative voltage supply. Its ease of integration, coupled with its robust protection features, makes it a top choice for designers looking to optimize their power supply solutions.
