SIMPLE SWITCHER Regulators Take Over Automotive Applications (Rev. A)


Power management applications, typically located on the front line of the automotive electronics system, can be subject to wide input operating voltage extremes resulting from load-dump and cold-cranking conditions. Careful selection of the power management electronics can provide added margin and protection to the automotive electronics system. The simplest design is provided by a power management switch-mode power supply, such as the LM2267x/80 family of SIMPLE SWITCHER® regulators, which integrates a power MOSFET and sustains a wide steady-state input voltage range.
