ISL6423ERZ-T

PMIC - Voltage Regulators - Special Purpose

ISL6423ERZ-T is a small package high frequency current mode buck regulator part of Intersil Corporation. This Voltage Regulator is especially designed for powering high-speed processors and digital logic. ISL6423ERZ-T is able to generate up to 10A of current, with an input voltage range of 3.04V to 18V, and output voltage ranging between 0.6V and 5.5V. This Voltage Regulator also has a thermal shutdown protection built-in, which ensures protection in case of any possible over heating.The ISL6423ERZ-T is mainly used in applications that require high-frequency, high-current processing and digital logic. Such applications include computers and engineering workstations, as well as portable electronic systems such as cell phones, PDAs, and other handheld devices.The ISL6423ERZ-T is designed to detect an input current condition and switch an output current accordingly. First, the input voltage is fed to the buck converter’s input stage, which measures the level of current. When the input current reaches the trip point voltage level, the converter’s control circuit turns the output current on. From then on, the control circuit periodically adjusts the output current to keep the input current level at the set-point. This process is referred to as “current mode control” and is a fundamental feature of the ISL6423ERZ-T.The ISL6423ERZ-T also includes some other features that are useful in increasing its performance. It includes an adjustable voltage reference, enabling fine-tuning of output voltage. Additionally, a slew rate control circuit allows for raising or lowering the ON/OFF rate of the output current. This feature is beneficial in applications that require a certain response time and can help limit the amount of switching noise.The overall performance of the ISL6423ERZ-T is enhanced by its advanced protection features. This Voltage Regulator includes a power good output indicator, which displays the status of the output voltage. Undervoltage protection circuit shuts the output off when the input voltage falls below the minimum value. In addition, the IC includes an overvoltage protection circuit, as well as an over temperature shutdown feature.The ISL6423ERZ-T is an ideal choice for powering high-speed processors and digital logic due to its high current handling capability and extensive protection features. In addition, the adjustable voltage reference and slew rate control feature provide additional flexibility and performance. Its small package size and low cost make it an attractive choice for a wide range of applications.
