Automotive designers face the challenge of adding more features to modern, high-end cars while using a compact and efficient solution that meets or exceeds EMI requirements. However, as more automotive features are added, the number of power lines also continues to increase. Each individual power line is fed from the car's battery through a buck converter and often requires specific voltage regulation accuracy. In addition to all these challenges, designers must comply with stringent industry safety standards.
The MAX20073/MAX20074 boasts higher efficiency than competing solutions and offers the lowest EMI in the industry, reducing interference that can affect subsystem function in a small solution size with ultra-low quiescent current. Combined with Maxim's unique spread spectrum oscillator, SYNC IN functionality, forced PWM, bypass modes, and current-mode architecture, system quality and performance are dramatically improved, simplifying overall system designs. Furthermore, point-of-load (POL) buck converters, such as the MAX20073/MAX20074, deliver highly specific voltages to the many power lines they come with, incorporating advanced modern features. Their output voltage accuracy makes them ideal for applications with tight memory and processor voltage requirements. The ICs also adhere to strict safety standards, operate with low input voltages over a wide temperature range, and minimize radio frequency interference (RFI) while exhibiting high accuracy, high efficiency, and high reliability.
Key Advantages
• Lower EMI: Exclusive spread spectrum and SYNC IN features mitigate system EMI radiation, making it easier for designers to meet EMI specifications.
• Higher Efficiency: Exhibits superior efficiency across the entire operating range for best-in-class efficiency compared to competing solutions.
• Small Solution Size: Its small 3-pin x 3 mm TDFN-EP package reduces the overall system footprint while saving on system bill of materials costs.
• Output Voltage Accuracy: The output voltage can be factory preset to allow ±1.5 percent accuracy without the need for costly external 0.1 percent resistors.
