MAX1760EUB

MAX1760EUB Description

The MAX1760EUB from Analog Devices Inc./Maxim Integrated is a high-efficiency, 1MHz synchronous boost DC-DC converter designed to deliver up to 1A of switch current. It supports an input voltage range of 0.7V to 5.5V, making it suitable for low-voltage applications, and provides an adjustable output voltage from 2.5V up to 5.5V (or fixed 3.3V). Packaged in a 10µMAX (ultra-thin µMAX) surface-mount form factor, this regulator is optimized for compact designs. Although marked as obsolete, its performance remains relevant for legacy systems requiring high efficiency (up to 95%) and synchronous rectification for reduced power loss.

MAX1760EUB Features

• Wide Input Range (0.7V–5.5V): Ideal for single-cell or low-voltage power sources (e.g., 1-cell alkaline/NiMH batteries).
• High Switching Frequency (1MHz): Enables smaller external components, reducing PCB footprint.
• Synchronous Rectification: Improves efficiency vs. non-synchronous alternatives.
• Adjustable/Fixed Output (2.5V–5.5V or 3.3V Fixed): Flexibility for diverse load requirements.
• 1A Switch Current: Supports moderate power applications.
• Compact 10µMAX Package: Suits space-constrained designs.
• Low Quiescent Current (40µA): Enhances battery life in portable devices.

MAX1760EUB Applications

• Portable Electronics: Powers handheld devices, sensors, or wearables from single-cell batteries.
• Energy Harvesting Systems: Efficiently boosts low voltages from solar cells or thermoelectric generators.
• Industrial/Medical Devices: Reliable for low-noise, compact power supplies in sensitive equipment.
• Legacy Designs: Replaces older non-synchronous boost converters for improved efficiency.

Conclusion of MAX1760EUB

The MAX1760EUB excels in low-voltage, high-efficiency power conversion, leveraging synchronous rectification and a 1MHz switching frequency to minimize size and loss. While obsolete, its wide input range, compact package, and 1A output make it a pragmatic choice for legacy or niche applications requiring robust performance. Engineers should evaluate alternatives for new designs but may still find value in existing inventories or specific low-power scenarios.
