Product Overview

IRDC3859 is an evaluation board which features the IR3859 synchronous buck regulator. It is a versatile regulator which offers programmability of switching frequency and current limit while operates in wide input and output voltage range. The MOSFETs copackaged with the On chip PWM controller make IR3859 a space efficient solution by providing accurate power delivery. This board has protection functions such as pre-bias startup, hiccup current limit and thermal shutdown to give required system level security in the event of fault conditions. An output over current protection function is implemented by sensing the voltage developed across the on-resistance of the synchronous rectifier MOSFET for optimum cost and performance.
  • Programmable soft start
  • Programmable over current protection
  • Integrated bootstrap diode
  • Enable input with voltage monitoring capability
  • Enhanced pre bias Start up
  • High bandwidth Error amplifier for excellent transient performance
  • Thermal protection
