Key Featrues
Adjustable Output Voltage (0.9V to 90% of VIN): The ability to program the output voltage from 0.9V up to 90% of the input voltage provides flexibility in meeting various load requirements. This feature enhances the regulator's versatility, enabling it to power a wide array of devices and components with precise voltage needs.
High Efficiency (>90%): With peak efficiency exceeding 90%, this regulator minimizes power dissipation, reducing thermal stress and improving overall system reliability. This is particularly beneficial in applications where energy efficiency and heat management are critical, such as base station power supplies and distributed supply regulation.
Internal Compensation for Any Output Voltage: This feature eliminates the need for external compensation components, simplifying the design process and reducing the bill of materials (BOM). It ensures stable operation across different output voltages, enhancing performance and reducing design complexity.
Adjustable Switching Frequency (100kHz to 2.2MHz): The ability to adjust the switching frequency allows designers to optimize the regulator for specific applications, balancing efficiency and electromagnetic interference (EMI). This feature is particularly useful in noise-sensitive environments, enabling better control over system performance and compliance with regulatory standards.
Applications
Distributed Supply Regulation: The MAX17574 is perfect for distributed power systems where multiple voltage rails are required. Its adjustable output voltage (0.9V to 90% of VIN) and high current capability (up to 3A) allow it to regulate power efficiently across various loads, making it ideal for complex industrial and automotive systems.
Industrial Control Power Supplies: The MAX17574 is well-suited for powering industrial control systems, such as PLCs and motor drives. Its robust design, including hiccup mode overload protection and overtemperature protection, ensures reliable operation in harsh industrial environments, while its high efficiency minimizes power dissipation.
Wall Transformer Regulation: The MAX17574 is an excellent choice for regulating power from wall transformers in consumer electronics and industrial applications. Its wide input voltage range and adjustable output voltage allow it to adapt to various transformer outputs, while its compact design and internal compensation reduce the need for external components, simplifying the design process.
