The MAX772ESA-T is a member of the DC DC switching controller family of products offered by PMIC (Power Management IC). It is an ideal solution for providing a regulated output voltage from an input source of varying voltage. The MAX772ESA-T provides an easy-to-use, reliable and efficient method for controlling and monitoring any DC to DC power supply.

The primary application of the MAX772ESA-T is in battery backed systems, where the input source is from either a solar panel, generator, rectified AC power source or a battery. When the input source is a battery, the MAX772ESA-T provides the necessary switching and control to maintain a constant output voltage, while preventing the battery from being over discharged.

The MAX772ESA-T is also an excellent choice for pulsed loads, due to its very fast transient response time. When the load current is changed, the MAX772ESA-T will quickly switch and regulate to the new load current. This ensures that the output voltage is both stable and accurate.

The MAX772ESA-T works by sensing the output voltage. When the output starts to deviate from its set point, the MAX772ESA-T automatically adjusts the duty cycle of its integrated Pulse Width Modulated (PWM) outputs, which in turn adjusts the current flow to the load to maintain the output voltage. This process is known as pulse-width modulation and is the basis for how the MAX772ESA-T works.

The MAX772ESA-T also includes built-in overvoltage and undervoltage protection, to prevent sudden spikes or drops in the output voltage. This protection ensures the stability and reliability of the device, even if the input voltage is varied or noisy.

The MAX722ESA-T provides many additional features, such as remote monitoring and control, a low-power shutdown mode, configurable soft-start, over-current protection and polarity reversal protection. It also has an adjustable current limit to ensure that the output current is within specified limits.

The MAX772ESA-T is available in a standard 6-pin SOT-173 package and is easy to use in any DC to DC converter or switching regulator circuit. Its features and versatility make it an ideal choice for battery backed systems, power converter designs and other applications where low-cost and reliable voltage regulation are needed.
