The ISL6568IRZA-T is a low voltage linear voltage regulator specifically designed for cell phone power management. It is part of the Power Management Integrated Circuit (PMIC) dedicated to providing system voltage regulation and high immunity temperature protection. It is categorized as a “Special Purpose” Voltage Regulator due to its unique ability to handle multiple cell phone power management challenges.

The ISL6568IRZA-T provides fast response time and low power consumption, which is important when it comes to mobile device power management. It is designed to handle a wide range of voltage levels, temperatures and load conditions. It can support up to 12V input and adjustable output of up to 2.5V with a wide range of line and load regulation. The voltage regulator is designed with high current capabilities to handle high current draws, up to 500mA.

The ISL6568IRZA-T has a wide temperature operating range of -40 to 85 °C, which ensures reliable performance even in extreme environmental conditions. The regulator is also equipped with in-built over-temperature protection, which helps protect the device from damage by limiting the device temperature for safe operation.

In terms of working principle, the ISL6568IRZA-T employs an integrated pulse width modulation (PWM) control technique to regulate the output voltage. This PWM scheme is used to regulate and switch the output voltage, thus providing very fast and accurate control of the output voltage. The voltage is regulated with peak current mode switching control and shared output control. Additionally, the use of an internal control loop allows for accurate regulation by minimizing output voltage deviation due to changes in the input and/or output load.

The working principle of the ISL6568IRZA-T involves controlling the output voltage by varying the output current. The input voltage is sensed and a current is then supplied to the output which is equal to the input voltage. The voltage is then adjusted and maintained by varying the output current by controlling PWM duty cycle. The on time and off time of the PWM control are used to regulate the output voltage to the desired level.

The ISL6568IRZA-T is a specialized voltage regulator specifically created for mobile devices, as it provides fast and accurate voltage regulation for mobile device power management. It is equipped with high current capabilities, wide temperature range and over-temperature protection, and utilizes pulse width modulation (PWM) control technique to regulate the output voltage. Its “Special Purpose” categorization sets it apart from other voltage regulators and makes it highly desirable for use in the portable device market.
