The IR3823AMTRPBF is a 3A easy-to-use, fully integrated synchronous buck regulator. It uses a compensation free fast Constant-On-Time (COT) control scheme, which simplifies the design effort and minimizes the bill of material (BOM). The IR3823A is offered in a small 3.5mm x 3.5mm PQFN package with excellent thermal performance.

Features

  • Wide input voltage range 4.3V to 17V
  • Precision Reference (0.6V +/
  • 0.5%)
  • Compensation free enhanced fast COT
  • forced continuous or diode emulation
  • Switching frequency from 0.6-2MHz
  • Enable input with voltage monitoring
  • PGOOD
  • power good output
  • Monotonic start-up
  • Two selectable soft start time
  • Enhanced pre-bias start up
  • Thermal shut down
  • Operating junction temp: -40°C to 125°C

Benefits

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