Integrating four power supplies in a 3 x 3-mm QFN package, the MAX20049 power management IC is claimed to deliver the highest efficiency on the market today. The device offers many options to support various output voltages, while also providing fault mitigation by flagging faults and shifts in output voltages.
"Designers have increasingly demanding constraints to adhere to when designing for the tiny components that go into cars, such as cameras modules, which is why there is a growing demand for more advanced power management ICs," says Chintan Parikh, executive business manager for the Automotive Business Unit at Maxim Integrated. "The MAX20049 meets ADAS design needs in terms of form factor, fault mitigation and power requirements, which translates to faster design cycles and quicker time to market."
The device, says the company, is almost 30% more compact than competitive solutions ((38 mm 2 compared to 53.3 mm 2)) and offers the highest efficiency among other quad-power power management ICs in its class. It offers many options to support modules that need various output voltages for different mixes of sensors and serializers, enabling designers to make changes in layout as needed or to fine-tune the IC to meet specific application requirements.
Other features include overvoltage and undervoltage monitoring, overvoltage protection, thermal shutdown, and short- circuit protection. Spread spectrum and 2.2-MHz switching mitigates electromagnetic interference (EMI) to meet CISPR low-noise specifications.
The MAX20049 is available now, pricing available on request. An evaluation kit - the MAX20049EVKIT - is also available.
