Maxim announced the availability of pin-compatible MAX20073 and MAX20074 buck converters to help automotive electronics designers significantly reduce EMI while improving efficiency. The compact converter provides the industry's lowest EMI, suitable for low-voltage point-of-load power supply designs, and it is ideal for automotive infotainment systems and ADAS applications.
Automotive electronics designers are adding more and more features to modern high-end cars, requiring the use of solutions that are efficient, compact, and meet or exceed EMI specifications. As more and more car functions, the number of power rails also increases. Each power supply is powered by a front-end buck converter powered by a car battery, which often has stringent regulation accuracy requirements. In addition to all the above challenges, designers need to meet the strictest industry safety standards.
The MAX20073/MAX20074 are more efficient and offer the industry's lowest EMI when compared to other manufacturers' competing products. They can effectively reduce the interference that affects the functionality of the subsystem. The solution size is very small, and the quiescent current is extremely low. Combining Maxim's unique architecture advantages such as the spread-spectrum oscillator, SYNC IN function, forced PWM, pulse-skipping mode, and current mode, system quality and performance are greatly enhanced, simplifying the overall design. In addition to the additional advanced features, back-end point-of-load (POL) bucks such as the MAX20073/MAX20074 also meet the stringent voltage requirements of many power rails. The device output voltage is very accurate, ideal for applications such as processors and memory that require very stringent voltage accuracy. The IC also meets stringent safety standards and can operate at low voltage inputs over a wide temperature range, minimizing radio frequency interference (RFI) and providing high accuracy, high efficiency, and high reliability.
