Maxim Integrated MAX848ESE+ High-Efficiency, Low-Noise, Step-Up DC-DC Converters

The Maxim Integrated MAX848ESE+ is a high-performance, step-up DC-DC converter designed to provide a reliable power supply solution for battery-powered and low-voltage systems. This compact, surface-mount device is part of Maxim's extensive range of power management integrated circuits, renowned for their efficiency, precision, and durability.

With its ability to boost input voltages as low as 0.7V to a selectable output voltage, the MAX848ESE+ is particularly well-suited for single-cell or dual-cell battery-powered applications where consistent power delivery is critical. It is an ideal choice for portable devices, such as handheld medical equipment, wireless sensors, and personal electronics, where space is at a premium and power efficiency is essential.

Key features of the MAX848ESE+ include:

• Wide Input Voltage Range: Capable of operating from input voltages between 0.7V to 5.5V, making it versatile for various low-voltage applications.
• Adjustable Output Voltage: The output voltage can be set from 2.7V to 5.5V using external resistors, allowing for flexibility in matching the power requirements of different loads.
• High Efficiency: Integrated synchronous rectification and a low quiescent current contribute to a high efficiency of up to 94%, minimizing energy loss during conversion.
• Low Noise Operation: The device employs a fixed-frequency, pulse-width modulation (PWM) control scheme that ensures low-output ripple and reduced electromagnetic interference (EMI).
• Compact Package: Supplied in a space-saving 16-pin narrow SO package, the MAX848ESE+ is suitable for high-density PCB layouts.
• Protection Features: Built-in thermal shutdown, over-current protection, and under-voltage lockout (UVLO) enhance the safety and reliability of the device.

The MAX848ESE+ is also easy to implement in a wide range of designs due to its minimal external component requirements. It only requires an inductor, capacitors, and two resistors to set the output voltage, simplifying the design process and accelerating time-to-market for new products.

Maxim Integrated's commitment to quality ensures that the MAX848ESE+ meets stringent performance standards, providing designers with a trusted solution for their power conversion needs. Whether you're developing a new portable gadget or upgrading an existing device, the MAX848ESE+ offers an optimal balance of efficiency, noise performance, and footprint for your power supply design.
