Component

boost converterSEPIC converter1.2 MHzDFN3*3-8integrated Schottky diode

XL6109 is a compact adjustable boost or SEPIC regulator for low-power rails from a 2.5 V to 25 V source. Its 650 mA rating is an internal switch-current limit, not a guaranteed 600 mA output-current rating.

Best for

  • Low-power boost supplies
  • Battery-powered 5 V rails
  • SEPIC rails where input can cross output voltage

Avoid if

  • Applications requiring a guaranteed 600 mA output current at all conversion ratios
  • Designs requiring documented automotive qualification
  • Applications requiring confirmed lifecycle or long-term supply status

Check before use

  • Peak inductor and switch current
  • Output-current capability at minimum input voltage
  • Inductor saturation-current rating
  • Thermal performance of the DFN exposed pad
  • Output voltage margin below 36 V protection
