MAX5086BATE+T is a high-performance integrated linear voltage regulator module in the field of power management. It provides highly efficient integrated power supply solutions for power conversion systems. This article will discuss the application field and working principle of the MAX5086BATE+T.

Applications

The MAX5086BATE+T integrated voltage regulator module is ideal for embedded applications that require high power efficiency and low power consumption. It is suitable for applications such as communications systems, industrial embedded systems, medical equipment, battery powered systems, portable hand-held devices, automotive power systems, and other applications.

The module is designed with an integrated linear voltage regulator and an over-temperature protection circuit that provides system protection against overtemperature conditions. In addition, the module features additional external current limit and voltage limit overhead regulators, which can provide extra power if required. It also supports reverse polarity protection and 5V tolerant inputs.

Working Principle

The integrated linear voltage regulator module is based on a buck - boost topology that provides high power conversion efficiency and very low output voltage ripple. The module uses an external voltage reference to provide the input voltage reference. This voltage reference is buffered and applied to the input of the regulator. The reference voltage is compared with the output sense voltage and the difference is used to adjust the output voltage. The regulator contains an internal DAC and error amplifier to sample and control the power transistor gate bias. The gate bias provides the control for the output voltage.

The MAX5086BATE+T module offers two different feedback voltage levels, allowing for wide operating range without the need for external reference voltage. The hysteresis of the error amplifier is adjustable with two programmable resistors. In addition, the module contains an over-temperature protection circuit to protect the system from high temperature conditions. The over-temperature protection circuit provides system protection even if the output load is over-current.

Conclusion

The MAX5086BATE+T is a high-performance, integrated voltage regulator module that provides an integrated solution to a wide range of power conversion systems. It is suitable for a variety of embedded application designs that require efficient power conversion and low power consumption. The module provides two different feedback voltage levels, allowing for wide operating range without the need for external reference voltage. It also contains an over-temperature protection circuit to protect the system from high temperature conditions.
