Maxim’s New Ultra-Small Step-Down Converters Ideal for Always-On Automotive Applications

Maxim revealed MAX20075 and MAX20076 that enable 50% savings in board space

Automotive ApplicationsMaxim Integrated introduces the ultra-compact,pin-compatible MAX20075and MAX20076 step down converters for system designers looking to create small land highly efficient40V load dump-tolerant applications. The MAX20075 and MAX20076 step-down converters offer the industry’s lowest quiescent current(IQ) and comes in an ultra-small size solution with integrated compensation. This enables minimal external components that can lead up to 50% savings in board space making them ideal products for always-on automotive applications.

Customers expect always-on applications to bring them experiences richer and more compelling than ever before. However, designers are challenged with having to balance delivering advanced features with meeting size constraints, power-saving features, and high efficiency.

“By offering the lowest IQ in the market, the pin-compatible MAX20075 and MAX20076 presents an overall benefit to the system. This translates to higher peak efficiency and faster start-up time,” said Chintan Parikh, Executive Business Manager, Automotive, Maxim Integrated. “The 3.5µA IQ offered with these buck converters are key to meeting stringent OEM quiescent current consumption requirements, which are typically as low as 100µA per module. This enables engineers to build in more processing power for more functionality and other advanced features.”

Key Advantages of the Maxim MAX20075and MAX20076 includes:

  • Industry’s LowestQuiescent Current: Offers 3.5µA IQ compared to traditional solutions that offer 15-30µA IQ; flexibility for more budget dispersed throughout the system; ability to support faster start-up times, consume lower power, and feature low minimum on-time operation mode
  • Highest Peak Efficiency: Delivershighest peak efficiency of 91% compared to competitive solutions
  • Ultra-Small Solution Size: 12-pin TDFN and side-wettable TDFN packages(3mm × 3mm) with integrated compensation enables very few external components for 50% savings in board space
  • EMI mitigation: Spread spectrum control and internally fixed at 2.1Mhz assist with CISPR25 Class 5 EMI compliance; supportsthe increasing need for more processing power inADAS applications

“Advancements in automotive technology have led to an increase in complex ECUs per vehicle. Adding more electrical components to a vehicle leads to higher amounts of parasitic battery drain, which has made reducing quiescent current a huge trend in the automotive world,” said Zong Zhen, Automotive Electronics and Semiconductor Senior Analyst for IHS Markit, a global information provider. “The MAX20075 and MAX20076 step-down converters offer another viable option to car manufacturers.”
