It is especially suitable for microprocessor, system and core voltage regulation. This device is popularly used in automotive applications, consumer electronics, communication infrastructure and industrial applications.

Features

The ISL6261ACRZ voltage regulator has many features that make it a popular choice for voltage regulation applications. It has a wide input voltage range of 3.0V to 18V and an adjustable output range of 0.7V to 13.5V. The device is capable of providing up to 4A continuous output current, with a switched current-limit of 7A. A PWM regulator enables variable frequency operation, with a spread of 100 Hz to 1 MHz.

The ISL6261ACRZ also has adjustable soft-start and so-called "DeadTime" features that allow the device to start up and stabilize quickly, even under heavy loads. The device includes Pre-BiasStart Up circuit, so the device can be used even in applications where the input voltage is not stable or slightly higher than the output voltage.

The device also includes complete thermal management, including built-in over temperature protection and pulse-by-pulse current limiting, as well as adjustable over voltage protection. Low-impedance EMI/RFI filtering circuitry is also included.

Application Fields

The ISL6261ACRZ is an extremely versatile voltage regulator and can be used in a variety of applications. It is particularly suitable for microprocessor, system and core voltage regulation. It is also popularly used in automotive applications, consumer electronics, communication infrastructure, industrial applications and other applications that require a stable voltage output.

Working Principle

The ISL6261ACRZ is a voltage regulator which works on the principle of controlling the voltage at the output by adjusting the amount of current flowing through the device. When the output voltage is too high, the device reduces the current, hence lowering the voltage at the output. When the voltage is too low, the device increases the current, thus raising the voltage at the output.

The ISL6261ACRZ has an integrated error amplifier which monitors the output voltage and controls the amount of current that passes through the device. The error amplifier compares the output voltage with a voltage reference and adjusts the output current accordingly. The error amplifier uses a series of resistors placed in the feedback loop to change the gain, thus controlling the output voltage.
