Automotive-grade, 1.2A step-down converter meets tight OEM power budgets

Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX16975* automotive-grade, 1.2A step-down converter optimized for operation over a 3.5V to 28V range. To accommodate extreme battery voltage variations in automotive applications, the device tolerates load-dump transients up to 42V and cold-crank excursions down to 3.5V. It can operate in dropout by turning on the integrated 300mΩ high-side FET for the duration of cold-crank or start/stop events. The wide input supply range, combined with an ultra-low quiescent current (45µA, no load), makes the MAX16975 ideal for automotive applications that have tight power budgets.
