Maxim Integrated MAX662AESA+T Voltage Converter

The MAX662AESA+T from Maxim Integrated is a highly efficient, monolithic, charge-pump voltage converter that stands out for its ability to deliver a regulated output voltage of 12V from an input voltage range of 4.5V to 5.5V. This makes it an ideal component for applications that require a stable 12V supply from a 5V logic power rail. The device is available in an 8-pin NSOIC package, making it compact and suitable for space-constrained applications.

One of the key features of the MAX662AESA+T is its high power efficiency, which is achieved through a switched-capacitor voltage doubler design. This design allows the converter to provide a high output current, up to 30mA, without the need for an inductor, reducing both the complexity and the noise typically associated with switching regulators. Additionally, the device includes an onboard oscillator, eliminating the need for external frequency-setting components and simplifying the design process for engineers.

The voltage converter also incorporates thermal shutdown and current-limiting features to protect against over-temperature and over-current conditions, ensuring reliable operation under a variety of circumstances. Furthermore, the MAX662AESA+T has a low quiescent current, making it suitable for battery-powered devices where power conservation is critical.

Applications for the MAX662AESA+T are diverse and include memory programming for computers and industrial systems, LCD bias supplies, and any other system that requires a regulated 12V supply. Its ease of use, combined with its small footprint and high efficiency, makes it an excellent choice for both prototyping and mass production.

Overall, the Maxim Integrated MAX662AESA+T voltage converter is a versatile and reliable solution for generating a 12V supply from a 5V input. Its integration of protection features and high efficiency, along with a compact package, make it an attractive choice for designers looking to streamline their power supply designs.
