The MAX1761EEE-T from Maxim Integrated is a high-efficiency, low-Dropout, step-down DC-DC converter designed to deliver a reliable and stable voltage supply for a wide range of applications. This versatile component is ideal for battery-powered devices, as it extends battery life by providing excellent power conversion efficiency and a quiescent current of only 110µA (typical).

Key Features

• High Efficiency: Capable of up to 95% power conversion efficiency, the MAX1761EEE-T ensures minimal power loss during operation, making it suitable for energy-sensitive applications.
• Adjustable Output: The output voltage is adjustable from 1.25V to 5.5V, allowing for a high degree of flexibility to match specific requirements of the powered device.
• Low Dropout: It operates with a low dropout voltage, which means it can continue to provide a regulated output even when the supply voltage is very close to the output voltage.
• Wide Input Voltage Range: The device accepts input voltages from 2.7V to 11V, accommodating a variety of power sources including single-cell to multi-cell batteries or regulated 5V and 12V power supplies.
• Small Package: The MAX1761EEE-T comes in a compact 16-pin QSOP package, making it suitable for space-constrained applications.

Applications

The MAX1761EEE-T is a versatile component that can be used in numerous applications, including:

• Portable and battery-powered devices
• Wireless and RF circuits
• PDAs and mobile phones
• Power supply modules
• Point-of-load conversions

Additional Information

Maxim Integrated's MAX1761EEE-T incorporates current-limit and thermal-shutdown features to protect against overcurrent and overheating conditions. The device also offers a shutdown mode, reducing the quiescent current to less than 1µA, which is ideal for power conservation in battery-operated systems. Its high-frequency operation (up to 500kHz) allows for the use of small, low-cost inductors and capacitors, further minimizing the overall solution size.
