[Introduction]: Recently, Maxim announced the introduction of buck converters to help automotive electronics designers significantly reduce EMI while improving efficiency. The compact converter offers the industry's lowest EMI for low-voltage point-of-load power supply designs and is ideal for automotive infotainment systems and ADAS applications.
Beijing, China – May 24, 2018 – Maxim announced the availability of pin-compatible MAX20073 and MAX20074 buck converters to help automotive electronics designers significantly reduce EMI while increasing efficiency. The compact converter offers the industry's lowest EMI for low-voltage point-of-load power supply designs and is ideal for automotive infotainment systems and ADAS applications.
Automotive electronics designers are adding more and more features to modern high-end vehicles, using solutions that are efficient, compact, and even better than EMI specifications. As more and more cars function, the number of power rails increases. Each power supply is powered by a front-end buck converter powered by a car battery, often with stringent regulation requirements. In addition to all of the above challenges, designers need to meet the most stringent industry safety standards.
Compared to competing solutions, the MAX20073/MAX20074 offer higher efficiency, provide the industry's lowest EMI, and effectively reduce interference that affects subsystem functions. The solution size is very small and the quiescent current is extremely low. Combined with Maxim's unique spread-spectrum oscillator, SYNC IN function, forced PWM, skip mode and current mode, the system quality and performance are greatly improved, simplifying the overall design. In addition to additional advanced features, back-end point-of-load (POL) bucks such as the MAX20073/MAX20074 can meet the stringent voltage requirements of many power rails. The device's output voltage is very accurate and ideal for applications such as processors and memories where voltage accuracy is critical. The IC also meets stringent safety standards and operates over a wide temperature range at low voltage inputs, minimizing radio frequency interference (RFI) and providing high accuracy, efficiency and reliability.
Main advantageLowest EMI: Unique spread spectrum and SYNC IN features effectively suppress system EMI, enabling designers to easily meet EMI specifications
High efficiency: achieve the highest efficiency in the entire work range compared to competitive solutions
Small size: Small, 3mm x 3mm, 10-pin TDFN-EP package reduces overall system footprint while saving system BOM cost
Output voltage accuracy: factory preset output voltage, output voltage accuracy of ±1.5%, no need for expensive 0.1% external resistor
Evaluation· "Designers need buck converters to meet today's increasingly stringent requirements, such as small size, ultra-high voltage accuracy and higher efficiency," said Warren Tsai, director of business management at Maxim Integrated Automotive. "MAX20073 and MAX20074 are upgrades." The newest member of the low-voltage, small-size POL buck converter family meets most system power requirements and passes pre-EMI testing."
Supply and price· The price of the MAX20073 is $1.20 and the price of the MAX20074 is $1.30; both devices can be ordered through the Maxim website.
· The device operates in the -40 ° C to +125 ° C ambient temperature range
· The MAX20073EVKIT# and MAX20074EVKIT# evaluation boards are available for $45.
· For pin-compatible ASIL devices, designers are advised to contact Maxim for details.
