The ISL6422BEVEZ-T is an ideal solution for a range of power management applications. This special purpose voltage regulator is designed to provide fast turn-on times, low output voltage ripple and low noise as well as a wide input voltage range and excellent thermal performance.

Application Field

The ISL6422BEVEZ-T is a perfect solution for any application that needs precise and reliable power management. This advanced voltage regulator can be used for on-board voltage regulation for telecommunications, aerospace and military applications as well as for batteries, industrial sensors, actuators and a variety of other products. This regulator is also suitable for use in distributed power architectures such as point-of-load converters and redundant voltage regulators. It is also suitable for applications in automotive and automotive aftermarket, avionics lighting and medical instruments.

Working Principle

The ISL6422BEVEZ-T voltage regulator is designed using advanced switching technology and is optimised to provide a tight load and line regulation with fast transient response times. This special purpose voltage regulator utilises an internal high frequency oscillator to switch up to six N-Channel MOSFETs, with each MOSFET controlling the output voltage of one phase.The ISL6422BEVEZ-T is capable of providing dynamic load regulation with a step load response time of less than 1µs and a stable regulation accuracy of ±2%. This feature is well-suited for applications where the load conditions constantly change.The output ripple of the ISL6422BEVEZ-T is very low, at a maximum of 10mV. This enhances its performance when used for applications requiring low output noise, such as communication systems.The input range of the ISL6422BEVEZ-T is from 6.5V to 25V and can withstand reverse voltage up to -25V. It is developed to support a wide input range of load current with a switching frequency up to 3 MHz, allowing it to support a wide range of voltage levels with an efficiency up to 95%.The ISL6422BEVEZ-T is also designed with advanced thermal protection disabling all power transistors should an over-temperature event occur, along with over-current protection to reliably protect it against overload. This advanced feature ensures that the circuit won’t be damaged even under extreme operating conditions.

Conclusion

The ISL6422BEVEZ-T is a perfect choice for applications requiring precision power management. This special purpose voltage regulator has a wide input voltage range, fast transient response times, low output ripple and excellent thermal performance, making it a great solution for distributed power architectures and other applications.
