Description The IFX91041 series are monolithic integrated circuits that provide all active functions for a step-down (buck) switching voltage regulator, capable of driving up to 1.8A load current with excellent line and load regulation. These devices are suited for use under the harsh automotive electronics environmental conditions featuring protection functions such as current limitation and overtemperature shutdown. Versions with a fixed 5.0V and 3.3V (IFX91041EJV50, IFX91041EJV33) output voltage as well as an adjustable device (IFX91041EJV) with 0.60V reference feedback...
