Maxim Integrated has announced power-management ICs offering a small solution size and high efficiency to help automotive designers meet space and power challenges of next-gen automotive applications. As digital instrument clusters, radio head units and electronic subsystems require ever higher levels of compute power.
These high power buck converters and high power, multiphase buck controllers empower designers to balance low power consumption with high efficiency and electromagnetic interference (EMI) mitigation.
As automotive systems become more sophisticated with increasing levels of electronic components, higher power microprocessors are required to control and supervise their functionality.
This adoption of more powerful instrument clusters, USB hubs, Advanced Driver Assistance Systems (ADAS) and infotainment and navigation systems is driving ten percent annual growth for power-management ICs through 2026, according to analyst firm IHS Markit.
This growth pattern is presenting designers with multiple challenges for managing power consumption, efficiency, EMI and solution size to achieve the performance needed in harsh, space-constrained automotive operating environments.
To ensure designers meet these goals, Maxim’s array of automotive-grade ICs provide many options to manage the DC power as automotive OEMs transition from processors that consume 20W of power to artificial intelligence platforms that consume as much as 500W.
With a package size of 3.5x3.75mm, according to the company Maxim’s buck converters offer the industry’s smallest solution size. Their flip-chip quad-flat no-leads (FCQFN) packaging reduces high frequency switch node ringing and eliminates bond wires to lower MOSFET switch on-resistance and increase efficiency.
According to the company, Maxim offers the industry’s only pin-compatible parts for four, six and eight amps for flexible power regulation. All of the ICs feature spread-spectrum modulation, high switching frequency, forced pulse-width modulation and skip-mode operation for suitable performance.
Maxim’s newest automotive power-management ICs for high voltage power applications include:
“Power semiconductors in automotive are projected to grow to more than $13.7bn by 2023,” said Kevin Anderson, Senior Analyst for Power ICs at IHS Markit.
“One of the high growth areas is the digital cockpit where engineers are introducing new features, more functionality and more powerful systems while staying within a finite area and power budget.”
“Today’s vehicles are powerful computers on wheels, with digital instrument clusters, radio head units and related subsystems requiring increasingly higher levels of compute power,” said Chintan Parikh, Executive Business Manager for the Automotive Business Unit at Maxim Integrated.
“Power supply designs must carefully balance low power consumption, high efficiency and EMI mitigation in order to meet the design challenges of these high voltage applications. High-power buck converters and multiphase, high power buck controllers play a critical role in enabling this technology.”
