Diodes Incorporated Launches 4A Buck Converter for Automotive Use
Diodes Incorporated Introduces AP61402Q: A High-Efficiency, Automotive-Compliant Buck Converter for Advanced Vehicle Systems
Diodes Incorporated, a leading global manufacturer and supplier of high-quality application-specific standard products within the broad discrete, logic, analog, and mixed-signal semiconductor markets, has unveiled its latest automotive-compliant power solution: the AP61402Q. This advanced 5.5V, 4A synchronous buck converter is meticulously engineered to deliver exceptional efficiency, ultra-low quiescent current, and a remarkably compact form factor, making it ideal for a wide array of demanding automotive systems. With its robust performance and stringent AEC-Q100 qualification, the AP61402Q is perfectly poised to support a diverse range of point-of-load (POL) applications within modern vehicles, including sophisticated infotainment systems, advanced driver-assistance systems (ADAS), and telematics modules.
Key Features and Benefits of the AP61402Q:
The AP61402Q is packed with features designed to optimize performance, minimize space, and ensure reliability in automotive environments:
Wide Input Voltage Range: Operates efficiently from 2.3V to 5.5V, offering versatile support for critical 5V, 3.3V, and core-voltage rails commonly found in automotive electronics.
High Output Current: Capable of delivering a robust 4A of output current, all within an ultra-compact V-DFN1515-6/SWP (Type UX) package, saving valuable board space.
Integrated Low Rds(on) MOSFETs: Features integrated 75mΩ high-side and 33mΩ low-side MOSFETs, significantly improving power efficiency by minimizing conduction losses and reducing the need for external components.
High 2MHz Switching Frequency: Enables the use of smaller, more cost-effective inductors and capacitors, directly contributing to a reduction in bill of materials (BOM) cost and maximizing board space efficiency.
Constant On-Time (COT) Control: Provides an inherently fast transient response and ensures low output voltage ripple, simplifying loop compensation and design complexity.
Ultra-Low Quiescent Current (Iq): Consumes only 20µA, ensuring excellent efficiency, especially under light load conditions, which is crucial for reducing power consumption in always-on automotive modules.
Flexible Operation Modes: A multi-function EN pin allows designers to select between PFM (Pulse Frequency Modulation) and PWM (Pulse Width Modulation) mode control, optimizing for either light-load efficiency or full-load performance.
Robust Protection Features: Incorporates comprehensive safety mechanisms including high-side and low-side current sensing, brown-out support, and essential thermal shutdown, enhancing the overall reliability and longevity of the system.
Automotive-Qualified: Fully AEC-Q100 qualified and manufactured at IATF 16949-certified sites, with complete Production Part Approval Process (PPAP) support, assuring compliance with the most rigorous automotive industry standards.
Target Automotive Applications:
The AP61402Q is specifically optimized for point-of-load (POL) power delivery within various critical automotive subsystems, ensuring stable and efficient power where it's needed most:
Infotainment Systems: Powering the diverse electronic components within car audio, navigation, and display units.
Instrument Clusters: Providing stable power for digital dashboards and vehicle information displays.
Telematics Modules: Essential for connectivity, emergency services, and fleet management systems.
Advanced Driver Assistance Systems (ADAS): Crucial for reliable operation of sensors, cameras, and processing units that underpin safety and autonomous driving features.
