The MAX629ESA+T is a DC-DC switching regulator developed by Maxim Integrated Products that features a low power consumption, high current capability, and low noise performance. It is primarily used in power management applications such as laptop computers, telephone systems, automotive electronics, wearable electronics and other low-power applications.

The MAX629ESA+T has a wide input voltage range, ranging from 4.75 to 30 volts, making it ideal for applications that require tight voltage regulation. It is capable of providing up to 1.2A continuous current, and has a high peak current capability of up to 10A. Additionally, the Max629ESA+T is designed for low-noise operation and is capable of providing clean, ripple-free output voltage. It has an integrated soft start and allows for adjustable frequency operation for improved board layout flexibility.

The MAX629ESA+T operates in either a voltage-mode or current-mode depending on the application. In voltage-mode applications, the voltage at the output is set by an external resistor. When set-up properly, the minimum output voltage is regulated very tight in order to provide a regulated voltage that is higher than that of the input voltage. In current-mode applications, the output current is set by an external resistor and the minimum output current is regulated much tighter in order to maintain the desired constant current output.

The MAX629ESA+T has specialized control circuitry for optimal transient response. This reduces the overshoot, undershoot and ringing that can occur with some switching regulators when a rapid step change in the load current occurs. It also provides adjustable dead time resulting in improved power conversion efficiency. The MAX629ESA+T features an output overvoltage protection that provides protection against inrush current and output voltage transients.

The MAX629ESA+T is well suited for applications that require low-power consumption and low-noise operation. It is suitable for use in battery-powered or portable devices, as well as in industrial applications where tight voltage regulation and low-noise operation are required. Additionally, it is an ideal candidate for extended temperature range applications, with an operating temperature range of -40°C to +85°C. It is available in a 5-pin SOT-23 package.
