MAX17220ELT+T is a voltage regulator that belongs to the category of DC DC Switching Regulators. It is a highly efficient, wide input voltage range and low power switch mode voltage regulator designed for portable power system applications. It operates from an input voltage range from 4.5V to 20V, providing an adjustable output voltage ranging from 0.8V to 15V. It offers a wide range of features for portable devices, including low noise, high efficiency, low output voltage ripple, and high voltage rating at its output.

The working of this DC DC regulator is based on two steps: first, the switching regulator steps up the input voltage to a required level, and then the linear regulator reduces the voltage from the switched dc level to the desired output voltage. To step up the input voltage, a switching regulator uses an inductor to convert the input voltage to a higher voltage. The integrated circuit switches the inductor on and off, providing higher voltage output than the input voltage. The switching regulator works in either buck or boost mode, depending on the load and application requirements.

Once the switching regulator has stepped up the input voltage, the linear regulator is used to reduce the voltage to the desired output level. Linear regulators operate by comparing the output voltage to a reference voltage and using feedback to adjust the voltage according to the differences in these two. The feedback adjustment is provided either by a sensing element or by a comparison of the output voltage with the input voltage. This regulator maintains the output voltage at a constant level, regardless of fluctuations in the input voltage.

By combining the features of both the switching regulator and linear regulator, the MAX17220ELT+T can provide a wide range of adjustable voltages from the same input source. The voltage regulator supports continuous current up to 1.5A and peak current of 4A. It is available in the adjustable and fixed-output versions. It is also available in surface-mount and through-hole packages, making it suitable for any application.

The MAX17220ELT+T also has several protective features to ensure the safe operation of the system. It has a thermal protection that disables the regulator circuit when the temperature exceeds a certain limit. It also has an under voltage lockout (UVLO) that prevents operation of the regulator when the input voltage is too low, and an overvoltage protection (OVP) to prevent output voltages from going above a certain level. This makes the voltage regulator suitable for use in a wide range of applications.

The MAX17220ELT+T is ideal for powering portable devices such as smartphones, laptops, and tablets. It is also suitable for applications such as solar inverters, DC to DC converters, USB power supplies, and power bank chargers. With its wide input voltage range, low power operation, and protection features, the MAX17220ELT+T is an extremely popular voltage regulator for powering devices that require an adjustable output voltage.
