Benefits
• Ultra-light load efficiency – up to 80% at 10mA
• Up to 95% efficiency
• Feedback reference accuracy as high as ±1%
Features
• Rapid-control architecture enables operation with
a high input/output voltage ratio (e.g., VIN = 19V
and VOUT = 0.8V) and small output capacitance
• Adjustable output voltage from 0.8V to 5.5V
• Universally compatible with most output
capacitors—stable with zero to high ESR
• Power good (PG) output
• Foldback current limiting and “hiccup” mode
short-circuit protection
• Safe start-up into pre-biased loads
Available Support
