1.8A DC/DC Step-Down Voltage Regulator 5.0V, 3.3V Or Adjustable Output Voltage

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 voltage are available. The switching frequency of 370kHz allows to use small and inexpensive passive components. The IFX91041 features an enable function reducing the shut-down current consumption to <2uA. The voltage mode regulation scheme of this device provides a stable regulation loop maintained by small external compensation components. Besides the feedforward control path offers an excellent line transient rejection. The integrated soft-start feature limits the current peak as well as voltage overshot at start-up.
