Maxim Integrated's MAX1722EZK+T Step-Up DC-DC Converter
The MAX1722EZK+T is a compact, high-efficiency, step-up DC-DC converter from Maxim Integrated, designed to deliver a stable and reliable power supply. This component is particularly suitable for portable devices, where extending battery life is of paramount importance. The MAX1722EZK+T operates from a minimum voltage of 0.7V, making it ideal for applications powered by single-cell batteries, including alkaline, NiMH, and lithium cells.
With its adjustable output voltage ranging from 2V to 5.5V, the MAX1722EZK+T provides flexibility for designers to cater to the power requirements of various circuits. This versatility is further enhanced by its high switching frequency of up to 500kHz, which allows the use of small, low-cost inductors and capacitors, thereby reducing the overall footprint and bill of materials for the end product.
One of the key features of the MAX1722EZK+T is its low quiescent current, which contributes to the extended battery life of the end device. Additionally, it offers a high efficiency of up to 95%, which is beneficial in minimizing heat dissipation and conserving energy. The device also includes a True Shutdown™ mode that disconnects the output from the input when disabled, ensuring minimal power consumption in standby mode.
The MAX1722EZK+T comes in a small 5-pin SOT23 package, making it suitable for space-constrained applications. Its ease of use is further exemplified by the minimal external components required for operation, simplifying the design process and accelerating time-to-market for products.
Protection features of the MAX1722EZK+T include over-current protection and thermal shutdown, safeguarding the device and the load from potential damage due to abnormal operating conditions. These features enhance the reliability and longevity of the end application.
In summary, the MAX1722EZK+T from Maxim Integrated is an excellent choice for designers looking to implement a step-up DC-DC converter in their power management solutions, particularly for portable electronics where efficiency, size, and battery life are critical considerations.
