Maxim Integrated MAX662AEPA Charge Pump Voltage Converter

The MAX662AEPA is a high-efficiency, CMOS charge-pump voltage converter manufactured by Maxim Integrated. It is designed to deliver a regulated output voltage of 12V from an input voltage range of 4.5V to 10V, making it an ideal component for applications requiring a boosted voltage level from a lower voltage power source.

This charge pump converter is housed in an 8-pin DIP (Dual In-line Package) and is characterized by its low quiescent current and high power efficiency, which makes it suitable for battery-operated devices. The MAX662AEPA is also capable of delivering a guaranteed output current of 30mA, which is sufficient for small to medium power needs in various electronic circuits.

The device incorporates an oscillator, a regulator, and control circuitry within its compact form factor. The built-in oscillator operates at a fixed frequency of 12kHz, which helps to minimize external components and simplifies the circuit design. Additionally, the MAX662AEPA features an automatic switching between step-up and step-down modes, depending on the input voltage, to maintain a stable output voltage.

One of the significant advantages of the MAX662AEPA is its ease of use. With minimal external components required, typically only two capacitors, designers can easily integrate this voltage converter into their systems. Furthermore, its thermal overload protection ensures safe operation under various conditions, while its high voltage conversion efficiency preserves battery life in portable applications.

Applications for the MAX662AEPA are diverse and include memory backup circuits, microprocessor power supplies, and any electronic system that requires a stable 12V supply from a lower voltage source. Its reliability and versatility make it an excellent choice for designers looking to extend the battery life of their products or to simplify the power management in their electronic designs.

In summary, the Maxim Integrated MAX662AEPA is a practical solution for a range of applications that require a small, efficient, and easy-to-use voltage converter. Its ability to provide a consistent 12V output from a lower voltage input ensures that it remains a popular choice for engineers and designers in the electronics industry.
