The IR3889 OptiMOS™ IPOL is an easy-to-use, fully integrated DC-DC buck regulator. The onboard PWM controller and OptiMOS™ MOSFETs with integrated bootstrap diode make the IR3889 a small footprint solution, providing high-efficient power delivery. Furthermore, it uses a fast Constant-On-Time (COT) control scheme, which simplifies the design efforts and achieves fast control response.

Features

  • Single 4.3-17V operation
  • Precision reference 0.8V +/
  • 0.5%
  • Enhanced fast COT engine
  • forced continuous or diode emulation
  • Switching frequency 0.6-2MHz
  • 4 selectable soft-start times
  • 4 setting OCP
  • Enable input with voltage monitoring
  • Thermal shut down
  • Operating temp: -40°C to 125°C
  • Small size: 5 mm x 6 mm PQFN
