The MAX764ESA, designed and manufactured by Maxim Integrated, is a high-efficiency, step-up DC-DC converter that is capable of delivering a fixed or adjustable output voltage from a lower voltage input. This device is particularly well-suited for battery-powered applications due to its low quiescent current and high efficiency across a wide range of load conditions.

Key Features

• Voltage Range: The input voltage range of 0.7V to 5.5V makes the MAX764ESA ideal for single-cell or multi-cell battery operations, as well as for standard 3.3V or 5V power supplies.
• Adjustable Output: The output voltage can be adjusted up to 30V with external resistors, providing flexibility for various design requirements.
• Efficiency: With efficiencies up to 94%, this converter maximizes battery life and reduces heat generation in portable devices.
• Low Quiescent Current: The low quiescent current of 110µA (typical) under no-load conditions contributes to the excellent efficiency and makes the MAX764ESA suitable for power-sensitive applications.
• Frequency Operation: It operates at a fixed 65kHz switching frequency, allowing for the use of small, low-cost inductors and capacitors.
• Pulse-Frequency Modulation (PFM): The PFM control scheme provides high efficiency over a wide range of load currents.
