Maxim Integrated MAX5023SASA-T High-Frequency, PWM Step-Down DC-DC Converters

The MAX5023SASA-T from Maxim Integrated is a high-performance, pulse-width modulation (PWM) step-down (buck) DC-DC converter designed for a range of applications requiring efficient voltage regulation. This compact and efficient component is ideal for portable devices, consumer electronics, and industrial equipment where space is at a premium and power efficiency is crucial.

With its wide input voltage range of 7.5V to 76V, the MAX5023SASA-T provides designers with the flexibility to accommodate various power sources, including multi-cell batteries or industrial power rails. Its adjustable output voltage can be set from 1.8V up to 90% of the input voltage, allowing for a broad range of output voltages to suit specific circuit requirements.

The device offers a fixed switching frequency of 300kHz, which strikes a balance between efficiency and component size, allowing for the use of smaller, less expensive inductors and capacitors. The high-frequency operation also enables a faster transient response, an important feature for applications sensitive to voltage variations.

The MAX5023SASA-T incorporates a range of protective features to ensure the reliability and longevity of the end application. These features include cycle-by-cycle current limit, thermal shutdown, and undervoltage lockout, which safeguard the device and the load from various fault conditions. Additionally, the soft-start feature minimizes inrush current at startup, reducing stress on the input power source.

Available in a compact 8-pin SOIC package, the MAX5023SASA-T is designed for easy integration into a variety of circuit layouts. Its surface-mount form factor is well-suited for automated assembly processes, helping to reduce manufacturing time and costs.

Maxim Integrated's commitment to quality and performance is evident in the MAX5023SASA-T DC-DC converter, making it a reliable choice for designers looking to create efficient, high-performance power management solutions.
