Maxim Integrated MAX8775ETJ+ Voltage Regulator

The MAX8775ETJ+ is a high-performance, triple-output, main power-supply controller for notebook computers, manufactured by Maxim Integrated. This advanced power management integrated circuit (IC) is designed to work efficiently in the demanding environments of portable computing, ensuring that the system operates with optimal power efficiency and reliability.

Featuring a triple-phase, synchronous-buck topology, the MAX8775ETJ+ provides a highly efficient solution for converting battery or adapter power to the core voltage required by high-performance CPUs. The device supports dynamic voltage scaling, which allows the CPU to operate at lower voltages during periods of reduced performance demand, thereby reducing power consumption and extending battery life.

The MAX8775ETJ+ integrates multiple functions to streamline power system design. It includes three high-frequency, PWM controllers for the CPU core, graphics core, and system agent rail. This integration not only saves space on the motherboard but also simplifies the design and reduces the bill of materials (BOM) cost for the power supply section of the system.

Key features of the MAX8775ETJ+ include:

• High efficiency with synchronous rectification
• Support for Intel IMVP-6+ and IMVP-6.5 CPUs
• Adaptive voltage positioning (AVP) for enhanced load-line accuracy
• Quick-PWM™ mode for fast transient response
• Power-good (PGOOD) outputs for each regulator
• Overvoltage, undervoltage, and overcurrent protection

The device is housed in a compact, 40-pin thin QFN (TQFN) package with a 6mm x 6mm footprint, making it suitable for space-constrained applications. Its operating temperature range of -40°C to +85°C ensures reliable performance across a wide range of environmental conditions.

With its advanced features and integrated design, the MAX8775ETJ+ from Maxim Integrated is an excellent choice for designers looking to implement a robust power management solution in their next-generation notebook computers.
