The MAX1771EP from Maxim Integrated is a robust and high-efficiency step-up DC-DC controller designed to provide a simple and reliable solution for power supply applications. This versatile device is capable of generating a regulated output voltage from an input voltage as low as 2V, making it ideal for battery-powered systems, and can operate with input voltages up to 16.5V.

Key Features

• Adjustable Output: The MAX1771EP allows for an adjustable output voltage, which can be set with external resistors, giving designers the flexibility to tailor the output to specific needs.
• High Efficiency: With its high switching frequency and low quiescent current, this controller achieves efficiencies up to 90%, thereby minimizing heat generation and extending battery life in portable applications.
• Low Voltage Operation: The device is capable of operating from inputs as low as 2V, making it suitable for applications with varying or low input voltages.
• Integrated MOSFET Driver: The inclusion of an on-board MOSFET driver simplifies the design and reduces external component count, providing a more compact power supply solution.
• No External Schottky Diode Required: Unlike many other step-up controllers, the MAX1771EP does not require an external Schottky diode, which can save space and cost.
