The MAX8863REUK+T is a linear voltage regulator from the range of PMIC (Power Management IC) devices from Maxim Integrated. It is designed to provide a robust and efficient power source for low and medium power products, such as data center servers, industrial and home appliance products, connected device applications, notebooks and gaming systems. The MAX8863REUK+T is an advanced high-efficiency, low-noise, high-capacity voltage regulator with a wide input and output voltage range.

The MAX8863REUK+T features a 2nm low-RDSON high-side MOSFET switch that is capable of dissipating up to 10A without the need of a heatsink. The high-side MOSFET requires only 0.7V of gate drive, allowing for a low 0.17Ω RDSON even at full-load. The device also includes a sleep-mode feature, which enables the device to enter an ultra-low standby current state to minimize power consumption for always-on applications.

The MAX8863REUK+T is designed to offer a wide range of protection features that are designed to maximize system durability and reliability. In the event of an output overvoltage, an overvoltage protection circuit will be activated to ensure that the power supply is shut down safely. In addition, the regulator also offers a feature that will maintain a minimum output voltage to ensure plenty of headroom for high-power devices that require a steady voltage.

The MAX8863REUK+T is also designed to reduce system startup current by up to 95%, eliminating the need for large external components. This is made possible thanks to the device’s low-input voltage range and its ability to detect when the power supply is inactive. When the supply is inactive, the input voltage is below the quiescent current detection threshold and the device will enter a low-power mode to reduce the input current.

The MAX8863REUK+T has a wide input voltage range of 4.5V to 14V and allows for output voltages between 0.6V and 5.5V. The device also features a low quiescent current of 70µA, making it ideal for mobile devices. Additionally, the regulator has a high maximum output current rating of 10A, allowing it to deliver the power needed for multiple high-current loads.

The MAX8863REUK+T is also designed to reduce power consumption and make it easier to optimize power delivery for improved energy efficiency. The EZPower™ feature allows for smooth regulation and dynamic load transient response, while the internal trickle charging feature helps eliminate the need for a dedicated battery charger. Finally, the device also includes a power-good signal and output enable/disable pin which allows the system to quickly enter a low-current state when the system is shut down or when the output voltage is out of range.

In summary, the MAX8863REUK+T is a high-efficiency linear voltage regulator from Maxim Integrated that is designed for working in applications with a wide range of input and output voltages, and offers robust protection features, low-power consumption and a high current rating. It is ideal for low and medium power products, such as servers, industrial and home appliance products, connected devices, notebooks and gaming systems.
