IR3846A OptiMOS™ IPOL is an easy-to-use, fully integrated DC-DC buck regulator with patented fast Constant-On-Time (COT) control scheme. It simplifies design effort with a small footprint, which fulfill customer needs for high power density. Meanwhile, IR3846A enables an enhanced transient response and improved Vout regulation with single switching frequency, thus it’s ideal for various applications looking for high efficiency, low EMI and compact solution.

Features

  • Wide input voltage range from 2-17 V
  • Precision Reference (0.6V +/
  • 0.5%)
  • Compensation free enhanced COT engine
  • Single Fsw for EMI-sensitive application
  • Continuous conduction for low Vripple
  • Enable input with voltage monitoring
  • Power Good Output
  • Enhanced pre-bias start-up
  • Fixed soft-start time
  • Selectable OCP limit
  • Thermal shut down
  • Operating Tj: -40 °C to 125 °C

Benefits

  • Easy to use fast COT PWM engine
  • High efficiency
  • Accurate output voltage regulation
  • Superior transient response
  • Reduced BOM
