Key Featrues
Triple-Output Synchronous Buck Controller: With three independent PWM controllers, the MAX15003 can manage multiple outputs simultaneously, each capable of delivering up to 15A. This feature is particularly beneficial for applications requiring multiple voltage rails, such as PCI Express® host bus adapters, improving overall system efficiency and performance.
Selectable In-Phase or 120° Out-of-Phase Operation: The device allows for selectable phase operation, which can reduce input capacitor ripple current and improve power supply efficiency. This feature is crucial for optimizing performance in high-density power management solutions.
Digital Soft-Start and Soft-Stop: The MAX15003 includes digital soft-start and soft-stop capabilities, which help minimize inrush currents and voltage spikes during power-up and power-down sequences. This feature enhances system reliability and longevity, especially in sensitive electronic applications.
Hiccup Mode Short-Circuit Protection: The hiccup mode short-circuit protection ensures that the device can safely handle fault conditions by cycling on and off during a short-circuit event. This protection mechanism prevents damage to the device and connected components, improving overall system safety and durability.
Applications
PCI Express® Host Bus Adapter Power Supplies: The MAX15003 is well-suited for powering PCI Express® host bus adapters, providing stable and adjustable output voltages down to 0.6V. Its ability to operate with a wide input voltage range (5.5V to 23V) and its programmable switching frequency ensure compatibility with various PCIe configurations, making it a reliable choice for adapter power supplies.
Point-of-Load DC-DC Converters: The MAX15003 is perfect for point-of-load (POL) DC-DC converters, where space and efficiency are critical. Its compact 48-pin TQFN package and external compensation allow for flexible design, while its lossless valley-mode current sensing ensures accurate current regulation, making it ideal for distributed power systems in industrial and telecom applications.
High-Performance Embedded Systems: The MAX15003 is an excellent choice for powering high-performance embedded systems, such as those used in automotive or aerospace applications. Its ability to handle multiple outputs with precise tracking and sequencing ensures reliable operation, while features like digital soft-start and hiccup mode short-circuit protection enhance system robustness and safety.
