Maxim Integrated MAX1790EUA Step-Up DC-DC Converter

The Maxim Integrated MAX1790EUA is a high-efficiency, compact, step-up DC-DC converter that is designed to deliver a stable and reliable voltage supply for a wide range of applications. This versatile component is housed in a small 8-pin µMAX package, making it an ideal choice for space-constrained applications.

The MAX1790EUA operates from an input voltage range of 2.7V to 5.5V, making it suitable for battery-powered devices, including single-cell Li-ion, or multiple-cell alkaline/NiMH applications. It can provide an adjustable output voltage from 2.7V to 5.5V, allowing designers to tailor the output to meet the specific requirements of their circuit.

One of the key features of the MAX1790EUA is its high efficiency, which can reach up to 94%. This efficiency is achieved through an internal synchronous rectifier and a 1.4MHz fixed-frequency PWM control scheme. The high switching frequency enables the use of small, low-cost capacitors and inductors, further reducing the overall footprint and cost of the power supply design.

The device also includes built-in safety features such as over-temperature protection and a low-battery detector, which ensures that the power supply remains reliable under varying operating conditions. Additionally, the MAX1790EUA offers a low quiescent current, contributing to extended battery life in portable applications.

For ease of use, the MAX1790EUA requires minimal external components, which simplifies the design process and accelerates time to market. Its internal compensation also reduces design complexity, making it a user-friendly choice for both novice and experienced engineers.

Whether it's for handheld devices, portable media players, or any other application requiring a high-efficiency voltage boost, the Maxim Integrated MAX1790EUA step-up DC-DC converter is engineered to meet the demands of modern electronic designs with its performance, compact size, and ease of integration.
