Maxim Integrated MAX758ACWE+ Step-Up DC-DC Converter

The Maxim Integrated MAX758ACWE+ is a high-efficiency, compact, step-up DC-DC converter that is designed to deliver a fixed or adjustable output voltage from a single-cell, two-cell, or three-cell battery input. This versatile component is ideal for portable devices where extended battery life is essential, such as handheld computers, medical instruments, and other mobile electronics.

The MAX758ACWE+ operates at a high switching frequency of 600kHz, enabling the use of small, low-cost inductors and capacitors, resulting in a space-saving solution that fits into tight PCB layouts. With its ability to step up voltages from as low as 0.7V, this converter can efficiently manage the power requirements of devices even as the battery voltage declines.

Key Features

• Adjustable output voltage from 2V to 16.5V or fixed 5V/12V
• High efficiency up to 87%, conserving battery life
• Low input voltage operation down to 0.7V, suitable for battery-powered applications
• 600kHz fixed-frequency PWM operation allows small, low-cost external components
• Low quiescent current, ideal for battery-powered devices
• Current-limited, pulse-frequency modulation (PFM) control scheme
• Thermal overload protection for safe operation
• Space-saving 16-pin wide SO package

With its integrated current-limit feature, the MAX758ACWE+ provides protection against overcurrent conditions, ensuring the longevity and reliability of your device. Additionally, the thermal overload protection prevents the converter from overheating, further enhancing system safety.

Whether you're designing for consumer electronics, portable medical devices, or any other battery-operated application, the Maxim Integrated MAX758ACWE+ offers a high-performance, space-efficient solution for your power conversion needs. Its ease of integration and robust feature set make it an excellent choice for engineers seeking to optimize their designs for both performance and size.
