Key Featrues
Silent Switcher Technology: This feature enables a compact, efficient, and low-EMI solution, making it ideal for sensitive applications like automotive and industrial systems. The spread-spectrum frequency modulation and symmetrical package design significantly reduce electromagnetic interference (EMI), ensuring compliance with CISPR 25 Class 5 standards and enhancing overall system reliability.
Wide Input Voltage Range (3V to 36V): The ability to operate across a broad input voltage range allows the IC to be used in diverse applications, from automotive systems to high-voltage DC-DC converters. This flexibility ensures stable performance even under varying power supply conditions, making it suitable for both low and high-power designs.
High Precision Output Voltage (±1% Accuracy): The IC provides precise output voltage regulation, ensuring consistent performance in critical applications like ADAS and infotainment systems. The ±1% accuracy in FPWM mode at no load, combined with the PGOOD signal for voltage monitoring, enhances system reliability and reduces the risk of voltage-related failures.
Dual-Phase Capability: This feature allows the IC to be used in dual-phase configurations, enabling high-power designs with improved efficiency and thermal performance. Dynamic current sharing through the shared VEA pin ensures balanced power distribution, while low-IQ operation in dual-phase mode further enhances energy efficiency in power-intensive applications.
Robust Automotive-Grade Design: With features like overtemperature and short-circuit protection, 99% duty-cycle operation, and a junction operating temperature range of -40°C to +125°C, the IC is built to withstand harsh automotive environments. Its 42V load-dump tolerance and AEC-Q100 qualification ensure reliable performance in safety-critical applications, reducing the risk of system failures.
