It can provide simple down conversion to output voltages as low as 0.6 V.

Key Features

  • 1 Power stage input voltage from 1 V to 16 V.
  • Control stage input voltage from 3 V to 6 V.
  • Output voltage adjustable down to 0.6 V.
  • Power-good flag and shutdown.
  • Output overvoltage and undervoltage detection.
  • ±2% Feedback voltage accuracy over temperature.
  • Low-side adjustable current sensing.
  • Adjustable soft start.
  • Tracking and sequencing with shutdown and soft- start pins.
  • Switching frequency from 50 kHz t.
