The IR3447AMTRPBF OptiMOS™ IPOL is an easy-to-use, fully integrated DC-DC buck regulator. It uses a fast Constant-On-Time (COT) control scheme, which simplifies the design effort and achieves fast control response. The onboard PWM controller and OptiMOS™ 5 MOSFETs with integrated bootstrap diode make the IR3447A a small footprint solution, providing high-efficiency power delivery.

Features

  • Wide input voltage range from 2-17V
  • Precision Reference (0.6V +/
  • 0.5%)
  • Compensation free enhanced COT
  • 600kHz switching forced conduction mode
  • 2ms soft-start time
  • Enhanced pre-bias start-up
  • Selectable OCP limit
  • Enable input with voltage monitoring
  • PGOOD
  • power good output
  • Thermal shut down
  • Operating temp: -40°C to 125°C
  • Small size:5 mm x 6mm PQFN

Benefits

  • Easy to use fast constant on-time
  • High efficiency
  • Accurate output voltage regulation
  • Superior transient response
  • Low BOM
