The MAX845ESA is a sophisticated, monolithic, CMOS charge-pump voltage converter manufactured by Maxim Integrated. This device is designed to provide a simple and efficient solution for generating a higher voltage from a lower voltage source. The MAX845ESA is particularly well-suited for small, battery-powered devices where space is at a premium and efficiency is crucial.

Key Features:

• High Efficiency: The charge-pump design allows for up to 99% power efficiency, making it an excellent choice for portable applications where battery life is critical.
• Wide Input Voltage Range: It operates from an input voltage range of +2.0V to +5.5V, accommodating a variety of power sources, from single-cell batteries to standard 3.3V or 5V power supplies.
• Adjustable Output Voltage: The output voltage can be set higher than the input voltage, up to double, by connecting a few external capacitors, which makes it highly versatile for different circuit requirements.
• Low Quiescent Current: The device boasts a low quiescent current, further conserving power when the device is in standby mode.
• Compact Size: Housed in an 8-pin SOIC package, the MAX845ESA saves board space and is ideal for space-constrained applications.

Applications:

• Portable Electronics
• Battery-Powered Devices
• Mobile Phones
• Handheld Instruments
• Medical Devices

The MAX845ESA is designed for easy integration into a wide range of electronic systems.
