  • 12A Continuous/15A Peak Output Current
  • 1% Internal Reference Accuracy
  • I2C Programmable Output Range from 0.6V to 1.87V in 10mV Steps with Slew Rate Control
  • 5% Accuracy Output Voltage and Output Current Read Back Via I2C
  • Selectable PFM/PWM Mode and Adjustable Frequency & Current Limit Through I2C
  • 4 Different I2C Address Selectable
  • External Soft Start
  • Open Drain Power Good Indication
  • Output Over Voltage Protection
  • Hiccup/Latch off OCP Protection
  • QFN-14(3mmx4mm) Package

Typical applications

  • Distributed Power Systems
  • Digital Set-Top Boxes
  • Solid State Driver (SSD)
  • Flat-Panel Television and Monitors
