IC revision1.2

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 in industrial applications featuring protection functions such as current limitation and over temperature shutdown.

Features

  • 1.8A step down voltage regulator
  • 3.3 V Output Voltage
  • ± 2% output voltage tolerance (+-4% for full load current range)
  • Integrated power transistor
  • PWM regulation with feed forward
  • Input voltage range from 4.75V to 45V
  • 370 kHz switching frequency
  • Synchronization input
  • Very low shutdown current consumption (<2uA)
  • Soft-start function
  • Input under voltage lockout
  • Suited for industrial applications: Tj = -40 °C to +125°C
  • Green Product (RoHS compliant)

Typical applications

  • Smart Metering
  • Building Automation
  • Industrial Automation
  • Medical & Healthcare
