The FAN1585ADX is a device that falls under the category of linear voltage regulators. It is a PolyPhase high power monolithic step-down pmic (power management integrated circuit) designed for charging applications such as laptops and desktop computers. It relies on switch-mode technology to regulate the output voltage in main applications like notebooks and PC systems.This device is designed to operate with a maximum input voltage of 12 V and has an adjustable output voltage range from 0.78 V to 5.5 V. The FAN1585ADX features low quiescent current, integrated power MOSFETs, and current-sharing, making it an ideal solution for high-powered applications.The FAN1585ADX utilizes peak inductor current-mode control to achieve fast transient response and accurate regulation. It features two integrated simple transient filters (SLTF) to reduce input ripple current and normal mode noise, providing improved signal integrity and system design flexibility. Furthermore, the FAN1585ADX comes with three integrated under voltage lockout (UVLO) options, meaning it can offer higher system reliability and lower component count.The FAN1585ADX is designed for main applications such as notebooks, PCs, and mobile computing devices. It is ideal for applications that require a high output current, such as battery charging and high-current load, because of its low quiescent current (30 μA) and high peak current capabilities.The FAN1585ADX operates as an integrated switch mode and linear regulator. In switch mode, the power MOSFETs switch the input voltage and the output voltage is regulated with thePower Good signal. In linear mode, the voltage is regulated by adjusting the internal reference voltage, allowing for more reliable control of the output voltage.The FAN1585ADX also offers a number of features that make it suitable for high-power applications. It features two operational modes, continuous mode and Pulse-Width modulation (PWM). In continuous mode, the device operates at a constant frequency and voltage, allowing for more reliable operation. In PWM mode, the device operates at a changing frequency and varying duty cycle to provide dynamic power control. The FAN1585ADX also features two digital functions, a reset/startup pin and a fixed/adjustable temperature compensation pins.In addition, the FAN1585ADX offers adjustable slew rate and soft start time, allowing for improved dynamic response and load response during startup. Additionally, the device offers over voltage and under voltage protection, further enhancing system reliability and robust operation.In summary, the FAN1585ADX is a highly integrated linear voltage regulator designed for main applications such as notebooks, PCs, and high-current loads. It offers low quiescent current, integrated power MOSFETs, and adjustability of output voltage, along with full protection features, making it an ideal solution for high-power applications.
