Key Featrues
No Current-Sense Resistor Required: By eliminating the need for a current-sense resistor, the design simplifies the circuit, reduces component count, and lowers power losses, enhancing overall system efficiency.
40/60 Optimal Interleaving: The interleaved operation at a 40/60 duty cycle reduces input capacitor requirements, minimizes ripple current, and improves power delivery efficiency, ideal for battery-powered devices.
Dual Mode Output Voltage: The device supports both fixed (3.3V/5V or 1.5V/1.8V) and adjustable (1V to 5.5V or 1V to 2.3V) output voltages, providing flexibility for various power supply configurations in notebooks, subnotebooks, and mobile communicators.
Independent PWM, Skip, and Low-Noise Mode Operation: Users can independently select PWM, skip, or low-noise modes, allowing optimization for efficiency, noise reduction, or performance based on specific application requirements, enhancing versatility in power management.
Applications
Battery-Powered Devices: The MAX8717 is well-suited for 2 to 4 Li+ cell battery-powered devices, such as PDAs and mobile communicators. Its wide input voltage range (4V to 26V) and adjustable output voltage (1V to 5.5V) allow for flexible power management, ensuring optimal performance and extended battery life in portable electronics.
Main or I/O Power Supplies: The MAX8717 is optimized for generating main (5V/3.3V) or I/O power rails in battery-powered systems. Its ability to operate in PWM, Skip, and Low-Noise modes makes it ideal for applications requiring precise voltage regulation and minimal noise, such as in industrial control systems or embedded computing.
High-Efficiency Power Controllers: The MAX8717 is perfect for high-efficiency power control in notebook computers and other portable devices. Its interleaved design reduces input-capacitor requirements and improves overall efficiency, making it suitable for applications where power consumption and thermal management are critical, such as in ultrabooks or compact laptops.
