##ISL95857IRTZ is a high-performance, integrated, cost-effective power-management integrated circuit (PMIC) designed specifically for mobile devices. It provides an ideal integrated solution for multiple power rail purposes in mobile devices. It is a high-density voltage regulator for mobile systems.The ISL95857IRTZ is a special step-down converter that provides a wide range of output voltage options, adjustable voltage positioning, dynamic voltage scaling, and consistent high efficiency across a wide input voltage range. With its advanced precision integrated circuit (PIC) and integrated Synchronous Rectifier (SR) technologies, it provides very low quiescent current (Iq) and outstanding power supply efficiency, reducing system power loss to an absolute minimum.The ISL95857IRTZ IC is compatible with high-density display and interface loads, enabling innovative applications in mobile phone designs that require multiple regulators, including LCD bias and backlight regulation, memory voltage regulation, and other low-voltage rails. It also features high-accuracy feedback regulation, high power-conversion efficiencies, and a wide input voltage range from 2.7V to 5.5V.Because of its multiple voltage rail requirements, the ISL95857IRTZ includes an integrated zero-crossing point Coulomb-to-DC converter and integrated switch mode power supply. The zero-crossing point technique allows for reduced switching losses and provides a more efficient power conversion solution than traditional linear regulators.The switch mode power supply enables synchronous operation of multiple rails while providing the highest power efficiency, lowest quiescent current, and best load-transient response compared to other regulators. The integrated switch mode power supply also allows for remote voltage control, which can help reduce system complexity and save board space by eliminating the need for extra components.The ISL95857IRTZ uses a Synchronous Rectifier for both its primary and secondary sides. The Synchronous Rectifier reduces switching losses significantly as compared to a diode rectifier, resulting in increased power efficiency and reduced power consumption. The ISL95857IRTZ also features an adjustable soft-start circuitry, active voltage scaling, and phase-offset modulation, which help minimize the inrush current and minimize EMI emissions. In addition, the ISL95857IRTZ includes numerous protective features such as input undervoltage protection, overvoltage protection, output overcurrent protection, and thermal shutdown. Overall, the ISL95857IRTZ is an outstanding power-management IC that provides outstanding efficiency, low quiescent current, and high-density integration all in a small package. It is an ideal solution for multiple power rail purposes in mobile devices and is compatible with high-density display and interface loads. With its advanced precision integrated circuit and integrated Synchronous Rectifier technologies, it provides very low quiescent current and great efficiency across a wide input voltage range.
