Maxim Integrated MAX662AESA-T Charge Pump Voltage Converter

The MAX662AESA-T from Maxim Integrated is a highly efficient, charge pump voltage converter that is designed to provide a reliable and stable voltage supply for various electronic applications. This compact, surface-mount device is an ideal solution for systems that require a negative voltage rail generated from a positive input voltage. It is especially suited for battery-powered devices, portable equipment, and other low-power applications where space and power efficiency are critical.

The MAX662AESA-T operates by converting a positive input voltage in the range of 4.5V to 10V into a corresponding negative output voltage, delivering a fixed output of -5V with an output current up to 20mA. This makes it an excellent choice for applications such as operational amplifier power supplies, bias voltage generation, and LCD panel power supplies, where a negative supply rail is needed.

One of the key features of the MAX662AESA-T is its high power efficiency, which is achieved through Maxim Integrated's proprietary charge pump technology. This technology allows the device to operate without the need for an inductor, thereby reducing the overall solution size and eliminating magnetic interference with sensitive circuitry.

The device comes in a small 8-pin SOIC package, which is ideal for space-constrained applications. Additionally, the MAX662AESA-T is characterized by its low quiescent current, typically only 300µA, which helps to extend battery life in portable applications. The converter also incorporates thermal overload protection and a power-saving shutdown mode that reduces the supply current to 0.1µA, further enhancing its suitability for low-power devices.

For designers and engineers looking for a reliable and efficient voltage conversion solution, the MAX662AESA-T is a versatile and practical choice. Its ease of integration, coupled with Maxim Integrated's reputation for high-quality semiconductor products, ensures that this charge pump voltage converter will deliver consistent performance and durability for a wide range of electronic designs.
