Maxim Integrated MAX797ESE-T High-Efficiency, Low-Noise, Step-Down DC-DC Converters

The MAX797ESE-T from Maxim Integrated is a highly efficient, low-noise, step-down DC-DC converter designed to meet the stringent power requirements of modern electronic devices. This versatile component is particularly well-suited for battery-powered applications where maximizing battery life is crucial, as well as for space-constrained applications that require a compact power management solution.

With an input voltage range of 2.7V to 5.5V, the MAX797ESE-T is capable of delivering an adjustable output voltage from 1.25V to VIN, making it compatible with a wide variety of devices and systems. It can supply up to 1.5A of output current, ensuring that even high-demand components receive the power they need to operate effectively.

The converter utilizes a synchronous rectification topology to achieve high efficiencies of up to 96%, reducing power loss and heat generation. This feature helps to prolong the life of the product and maintain a lower operating temperature. The MAX797ESE-T also boasts a low quiescent current, which is ideal for battery-powered equipment, as it minimizes the drain on the battery when the device is in standby mode.

One of the key features of the MAX797ESE-T is its low-noise operation. The device uses a fixed-frequency, pulse-width modulation (PWM) control scheme that significantly reduces the noise and ripple, making it an excellent choice for noise-sensitive applications such as RF communications and precision instrumentation.

Additional features include internal digital soft-start, which prevents inrush current at startup, and a Power-OK (POK) output that indicates when the output voltage is within nominal operating range. The MAX797ESE-T also provides comprehensive protection features such as over-temperature protection and current limit to safeguard against adverse conditions.

The compact size of the MAX797ESE-T is encapsulated in a 16-pin narrow SO package, making it easy to integrate into a variety of circuit designs without taking up excessive board space. Whether for portable devices, wireless systems, or distributed power systems, the MAX797ESE-T delivers the performance and reliability expected from a leading power management solution by Maxim Integrated.
