Nano power DC-DC converter in GF 22FDX with ultra-low quiescent current and high efficiency at light load

Key Benefits

  • - Ultra-low quiescent current (300 nA) to ensure minimum current consumption in deep sleep / hibernation mode
  • - High efficiency at light load to extend battery lifetime (75% @ 10 uA)
  • - Low ripple value to supply noise sensitive and RF loads
  • - 1 uH inductor
  • - Ultra-small area for reduced silicon cost
  • - Configurable output current (depending on application requirements)
