Maxim Integrated MAX8790ETP+TG: High-Efficiency, Quad-Output, Main Power-Supply Controllers for Notebook Computers

The MAX8790ETP+TG from Maxim Integrated is a state-of-the-art power-supply controller designed specifically for the demanding needs of notebook computers. This advanced controller is part of Maxim's commitment to providing high-performance, compact, and energy-efficient solutions for portable electronics. The MAX8790ETP+TG is optimized to deliver a highly efficient power management system with its quad-output configuration, making it an ideal choice for designers looking to maximize battery life without sacrificing performance.

This versatile controller features a multi-phase buck topology that significantly improves efficiency and reduces the thermal stress on components by distributing the power load across multiple phases. It is capable of driving up to four synchronous-rectified buck channels, which makes it a perfect fit for powering the CPU core, graphics processor, memory, and system chipset in notebook computers.

The MAX8790ETP+TG boasts an impressive array of features that enhance its performance and reliability. It includes a high-frequency operation up to 1MHz per phase, which allows for the use of small, low-cost capacitors and inductors, reducing the overall solution size and cost. Additionally, it offers precision overvoltage, undervoltage, and overcurrent protection to safeguard the system against potential damage from abnormal operating conditions.

With its adaptive voltage-positioning (AVP) and active voltage-positioning (AVP) modes, the MAX8790ETP+TG ensures tight load-transient regulation, which is critical for maintaining stability and performance in fast-changing load conditions. The device also features a Quick-PWM™ mode that provides lightning-fast transient response, further enhancing the stability of the power supply system.

For ease of integration, the MAX8790ETP+TG is available in a thermally efficient, 48-pin thin QFN package, and it operates over the extended -40°C to +85°C temperature range. Designers can take advantage of Maxim Integrated's comprehensive support and documentation to streamline the development process and bring their products to market faster.

In summary, the MAX8790ETP+TG from Maxim Integrated represents a powerful, flexible, and efficient solution for the power-supply needs of modern notebook computers, offering a combination of performance, protection features, and compact design to meet the rigorous demands of today's mobile computing applications.
